Milo BRAND + INTERFACE SYSTEM V1.2
24Image Usage

Where the image goes. At what size. Credited.

05 Imagery says what the engine can do and 06 and 19 show the collections. This page is placement: which surface gets an image, in which position and ratio, with which treatment and caption, and whether it is allowed to move. The mix is 60 stylized, 30 natural, 10 animated, and the rules below make it hold on every screen.

The mix24.0

Sixty stylized. Thirty natural. Ten alive.

Counted across a surface, not a page, and never enforced by a script. One animated image in view at a time is the only hard rule.

■ 60% STYLIZED · a recipe derivative■ 30% NATURAL · the clean source▨ 10% ANIMATED · engine/fx.js
+What counts, and what the colour rule means
StylizedAny of the five recipes (National Park, Nous, Archive, Paint, Field Study) shipped as a static derivative. Counts once per placement.
NaturalThe credited source uncropped, or the 1200px web derivative. Thumbnails in galleries count as natural.
AnimatedAn image carrying data-fx. It counts as animated whatever its source; it does not also count as stylized.
ColourV1.3: a rule, not a lean (D-051). About 60% Vermilion / Moss / Carbon / Cream treatments, 30% the source's own colour, 10% the animated colour shifts — and the page around the images follows the same 60 / 30 / 10 as a colour rule: ground, structure, signal (02.6). Was: "a lean, not a ratio to hit".
ScopeA surface is a screen or a design-system page. Today with one natural figure is 0 / 100 / 0 and correct; the mix is met across the product, not inside every view.
Placement by surface24.1

Operational surfaces carry almost none. Editorial ones carry one that matters.

Six surfaces, one row each: position, ratio, treatment, caption, and whether animation is allowed there.

Tasks, Activity, Costs, Fleet, Connections and Settings carry no imagery at all. A machine row shows a glyph, not a photograph of the machine. The exception is Work / Artifact when the artifact is itself an image: then it is shown natural, in the viewer composition, with a full caption.

Do / don't24.2

Five pairs, rendered live.

Each pair is the same image placed twice. The left holds the rule; the right breaks it, and the caption says which principle it breaks.

Loosened in V1.3. Several don'ts on this page were really permissible, so four are now marked ✓ Permitted, each with the condition it needs and why it is now allowed. The placement rule is stated plainly in 24.5: the head sits naturally, 50 / 50 is the preferred start, and a too-low or too-high crop is named as such. Everything else stays a don't, and the list below says why.

+What changed in V1.3 — four now permitted, seven kept
  • ✓ PERMITTED · MORE THAN ONE ANIMATED IMAGE IN VIEWWhen they run on one clock (engine/fx.js since V1.3): entrances start 450 ms apart and glitch bursts never overlap, so the plates take turns instead of competing. A Pause motion control is on every page that moves.
  • ✓ PERMITTED · NATIONAL PARK ON A DARK GROUNDIn galleries and viewers in dark mode, and on campaign surfaces as a lit print on a dark wall. A gallery shows the work as it is; the theme does not get to choose the recipe.
  • ✓ PERMITTED · A HEADLINE ACROSS THE WHOLE PLATEOn campaign surfaces only (poster, launch, social), where type and image are one object — 33 Expression Levels already gives campaign 70% expression. It must land on a quiet region and reach 3:1 as large text, or take a field.
  • ✓ PERMITTED · A LABEL ON THE SUBJECTAs a Field Study annotation of a measured feature: a mono label with a leader to the thing it names, at 4.5:1, never across a face. Natural-history plates have always labelled the specimen.
  • ✕ KEPT · CROP THROUGH A FACEThis is the placement rule, not taste: the head is whole and naturally placed or the ratio is wrong.
  • ✕ KEPT · AN UNCAPTIONED IMAGEProvenance is the reason the collection exists; an image without its artist is wallpaper.
  • ✕ KEPT · A PLATE BEHIND AN OPERATIONAL STATEMENTToday, Tasks and Costs are for deciding. Hierarchy wins there.
  • ✕ KEPT · SERIF DIRECTLY ON DITHER · BODY COPY ON AN IMAGE · CREAM TYPE UNDER 4.5:1Three legibility rules. WCAG AA is the floor at every expression level.
  • ✕ KEPT · MOSS OR CREAM TYPE ON NOUSMoss means Offline (D-011); on a Nous plate it claims the image for infrastructure.

Crop respects the work.

A crop may tighten; it may not cut through a face, a signature, or the subject the title names. Use object-position to keep the subject; if no position works, change the ratio.

Do
Leonardo, Head of the Virgin, crop keeps the head
Leonardo da Vinci
The Head of the Virgin in Three-Quarter View

4:3 with object-position: 50% 30%. The head sits whole; the empty sheet below is what was cut.

Don't
Leonardo, crop through the face
Leonardo da Vinci
The Head of the Virgin in Three-Quarter View

21:9 forces a band through the face. The ratio was chosen for the layout, not the work. Aesthetic-usability does not excuse it.

The artist is named every time.

An image without a caption is wallpaper. The caption variant may be compact or a stamp, but the artist or agency is never absent from the frame.

Same image, no caption. It now reads as a Milo texture. The transformation is presented as the work. Provenance is lost at the point of use.

Animated images take turns.

Was: one animated image in view. Two moving plates on independent clocks compete; the eye stops reading and starts watching. Since V1.3 every animated image runs on one clock, so more than one may share a view — they take turns.

Two bursts on independent clocks. This is the only place on the site where it happens, and it is here so the difference can be felt. Signal-to-noise fails.

WHY IT IS NOW ALLOWEDThe two plates here no longer run on independent clocks: the engine staggers their entrances by 450 ms and never lets two glitch bursts overlap, so they alternate. Condition: never beside a column of body text, and the page carries the Pause motion control.

Operational screens stay operational.

Today, Tasks and Costs are for deciding. A stylized plate there competes with the one thing that matters. A small natural figure below the fold is the most an operational surface carries.

Half Dome National Park recipe behind text

Cut the Daily Bread Day 4 opener.

National Park full-bleed behind the statement. Type on a photograph, a stylized image on an operational screen, and the decision now has to be read through vermilion. Hierarchy and signal-to-noise both fail.

Nous on dark. National Park on light.

Recipes have a ground. Nous is built for carbon; its stone highlights and vermilion signal read on black. National Park is built for cream. Swap them and the plate fights the surface.

Do
Earthrise, Nous, on carbon

Earthrise · MILO / NOUS

Carbon ground, Nous plate: the black of the image and the black of the surface are the same black. The vermilion is the only event.

Permitted, with a condition · was: don't
Earthrise, National Park recipe, on carbon

Cream highlights on a carbon surface: the plate becomes a lit rectangle and the page around it goes dead. Wrong ground for the recipe.

WHY IT IS NOW ALLOWEDIn a gallery or viewer in dark mode the work is shown as it is — the theme does not get to choose the recipe — and on a campaign surface a lit print on a dark wall is the point. Still the wrong choice for an editorial plate you are composing on carbon: reach for Nous there.

CadenceV1.3: every entrance starts on full reveal (the whole image in view, or 85% of the viewport for a taller image, held 240 ms). Reveal 3.6 s once (--dur-dither-reveal); pixels 2.8 s once (--dur-image-resolve); drift 5.2 s per breath, continuous; glitch bursts 0.9 s, 3–4.5 s apart while fully in view (--dur-glitch-burst, --dur-glitch-gap, or data-fx-interval); scan 9 s; band 16 s; swap 3.6 s then holds 5.2 s.

Crop rules · placement24.5

Position the subject, then choose the ratio.

The head sits naturally: eyes on or near the top third, a little air above the crown, nothing cut. Start at 50 / 50 — it is the preferred look — and move only if the head sits too low or too high.

A little too low
Rembrandt, Aristotle, framed at object-position 50% 0%: the head sits low with too much dark space above it
Too much air above the hat; the eyes fall below the top third and the figure sinks.object-position: 50% 0%

The head is pushed to the top edge and the hat is cut. A crop like this is a detail, and must be captioned as one.object-position: 50% 100%

V1.2 labelled the left frame "ship" and the middle "cuts the head". Looked at again, the middle is the natural placement and the left sits too low; corrected in V1.3 (D-049).

+Rules
PlacementThe head is naturally placed. Eyes on or near the top third of the frame; a little air above the crown; nothing of the head cut. Too much air above it and the figure sinks (too low); the crown at or past the top edge (too high).
DefaultStart at object-position: 50% 50% — the preferred look — and check the head against the placement rule. Move it only if the head sits too low or too high, and write the value you chose on the element. (V1.2 said "never rely on 50% 50%"; amended V1.3.)
Then the ratioIf no position places the head naturally at the layout's ratio, the ratio is wrong for the work: change the ratio, not the head.
Faces and signaturesWhole or absent. A crop that shows part of a face is a detail and must be captioned "detail".
LandscapesKeep the horizon out of the vertical centre. Prefer the top third for skies that carry Vermilion, the bottom third for land that carries Moss.
Prints and drawingsNever crop the margin off a print or the sheet edge off a drawing at full or compact size; the margin is part of the object.
PhotographsRatios are free; the source's own aspect is preferred for natural placement, 4:5 or 21:9 for plates.
SpaceNASA imagery may be cropped to the subject; the field is not the work.
Type on image24.7

Type sits on paper, not on paint.

Six rules for the only two kinds of type that may touch an image: a serif statement inside a cream field, and mono metadata at the edge. Everything else stays off the picture.

a · Serif in a field, or on the paper area.

A display statement over a National Park plate lives inside a cream field, or on a region the recipe already left as paper. The field is the block; the statement is what it holds.

Do
Half Dome, National Park, serif inside a cream field

What shall we make today?

HIGHSMITH · HALF DOME · LOC

Cream field, carbon serif, one vermilion word; the metadata takes its own small cream field because the trees are dither. Contrast is the field's, not the plate's.

Don't
Half Dome, serif directly on the dither

What shall we make today?

Cream serif on vermilion dither: the counters fill with dots, the contrast changes word by word. Legibility depends on the image.

b · Mono metadata at the edge.

A mono line may sit directly on the image, inside the padding, top-left or bottom-right. Carbon on a light area, mineral on a dark one. Never mid-image.

Do
Earthrise, Nous, mono metadata at the cornersAS08-14-2383 · 24 DEC 1968NASA · MILO / NOUS

Two corners, mineral on carbon, the image untouched between them.

Permitted as an annotation · was: don't
Earthrise, metadata across the middleAS08-14-2383 · 24 DEC 1968 · NASA

The line crosses the Earth. Metadata is a margin note; it does not annotate the subject.

WHY IT IS NOW ALLOWEDA label on the subject is the oldest device of the natural-history plate, and Field Study is built from it. Allowed when it names a measured feature (a crater, a limb, a coastline) with a short leader, in mono at 4.5:1, never across a face. A caption line crossing the picture, as here, is still a margin note in the wrong place.

c · Never body copy on an image.

Reading length text has one ground: the surface. If a paragraph needs to be near an image, it sits beside it or below it in the caption composition.

Do

Church painted Heart of the Andes from sketches made on two journeys to Ecuador and Colombia. When it was shown in New York in 1859 people paid to see it and brought opera glasses.

Church, Heart of the Andes, natural

Text left at five columns, image right at seven. The paragraph reads at full contrast.

Don't
Church with body copy on the painting

Church painted Heart of the Andes from sketches made on two journeys to Ecuador and Colombia. When it was shown in New York in 1859 people paid to see it.

A paragraph on a painting: the painting is defaced and the paragraph is unreadable. Both lose.

d · The headline may cross the edge. Once.

The one editorial move: a display statement that starts on the surface and overlaps the plate by one or two columns. It is allowed once per page, on the hero, and the overlap lands on a quiet part of the image.

Do

Art. Nature. Intelligence.

Grand Teton, National Park, headline crossing the left edge

Columns 1–6 for the statement, 5–12 for the plate: a two-column overlap onto the plate's cream sky.

Permitted on campaign · was: don't

Art. Nature. Intelligence.

Headline running across the whole plate

The statement runs the width of the plate: no longer a crossing, now type on an image, and rule (a) applies.

WHY IT IS NOW ALLOWEDOn a poster, launch screen or social card, type and image are one object; 33 Expression Levels gives campaign 70% expression, and this is what that looks like. Condition: campaign only, the words land on a quiet region (sky, paper), and every glyph reaches 3:1 as large text or the words take a field. Editorial pages still cross once, on the hero.

e · On Nous, only mineral or vermilion.

Nous plates are carbon. Type on them is mineral white for metadata or the vermilion word for a statement inside a carbon field. Cream and moss type never touch a Nous plate.

Do
Pillars of Creation, Nous, mineral and vermilion typeM16 · 6,500 LY◉ MILO / NOUS

Mineral metadata, one vermilion signal. The plate's own palette.

Don't
Pillars with moss and cream typeM16 · 6,500 LY⌁ LOCAL

Moss on Nous reads as infrastructure claiming an image. Two semantic colours on one plate.

f · 4.5:1 or a field.

Any type on an image must reach 4.5:1 against the pixels behind every glyph. If the image cannot guarantee it — and a dithered plate cannot — the type goes into a field. The field is the fallback; it is also the default.

Do
Monet, Water Lilies, caption in a cream field
CLAUDE MONET · WATER LILIES · 1906 · AIC

The field guarantees the ratio regardless of what is behind it.

Don't
Monet with cream metadata directly on the waterCLAUDE MONET · WATER LILIES · 1906 · AIC

Cream on lily-pad green measures about 2.2:1. A caption that cannot be read has not credited anyone.
