Theme Accent Mode Density

Contrast

Text against what it sits on. Below 4.5:1 fails WCAG AA for body text — the check a reviewer runs on any surface that takes a tone.

Waiting for the first preview to report its palette.

Brand 5

The accent seam an app actually brands itself through. Change these and you have made the decision a real `DesignTokens.graphite(...)` call makes.

accent The one voice of color — a BRAND SLOT — as a FILL (`--accent`, `Brand.d.ts` THE ACCENT'S TWO JOBS, #1689): a surface painted with the accent under [onAccent] (a slab, the FAB, a count badge, a checked box's face, an on switch's track, an active toggle's face, a pin head, a band under `chrome: accent`) and every wash mixed from it ([accentTint], [accentSel], [focusHalo], [groundGridInk], the deep chrome). Drawn ON a surface, the accent is [accentInk]. onAccent Foreground color painted on top of [accent]. accentInk THE ACCENT'S INK (`--accent-ink`, #1689): the accent drawn ON a neutral or washed surface — text and links, a glyph or icon, a border, an edge or underline, a selection start-edge, the focus ring and a field's focused border, a radio's dot, a status marker, a progress bar or spinner, the chart's lead series, the palette's `accent` ink. THE BOUNDARY OF A FILLED STATE IS INK: a checked box, an on switch and an active toggle draw their edge in it over the [accent] fill. Absent from the brand it IS [accent], byte for byte; a brand whose accent is a high-luminance hue states a darker ink of the same hue, and the plane-contrast gate holds this, not the fill, to the card and the ground (`contrastFloorViolations`). accentTint The accent at 9% (16% dark) — ID chips, the active row's wash, an applied chip, an applied-but-closed control (`--accent-tint`, derived from [accent]). accentSel The accent at 11% (18% dark) — the rail's FILLED INDICATOR (M3), laid over the GROUND, a step stronger than [accentTint] because the ground is darker than the card (`--accent-sel`, derived from [accent]).

Geometry 15

Square or rounded, and how heavy every line is. The radius row above the controls sets all three corners at once, because "what does square feel like" is one decision rather than three numbers.

rXs Radius for chips, checkboxes, tags, badges (`--r-xs`, 2). rS Radius for controls: buttons, fields, map pins and clusters (`--r-s`, 3). rM Radius for surfaces: cards, menus, dialogs (`--r-m`, 4). rL Radius for a sheet's leading corners, the largest surfaces (`--r-l`, 8). rMark Radius for a status marker, a legend swatch (`--r-mark`, 1). rPill THE PILL FLOOR (`--r-pill`, #1102): 0 in every corners set but [CornerStyle.round], where it is 999 and clamps to height / 2. A pill-capable control reads [controlRadius] or [chipRadius], never this directly. hairline Hairline stroke width. iconStroke Icon stroke weight. focusW Focus ring stroke width (solid [accentInk], offset [focusOffset]). focusHaloW The width of a FIELD's focus halo (`--focus-halo-w`, 3): a focused field takes the [accentInk] border plus [focusHalo] this wide OUTSIDE the box — the idiomatic Flutter form is a [BoxShadow] with this `spreadRadius` and zero blur. ctl Control height: buttons, toolbar (44 comfortable · 32 compact). fld Field box height: text fields, selects, date fields (`--fld`, 44 comfortable · 36 compact) — a field box stays a step taller than a control at the desk. navh Nav row height (44 comfortable · 34 compact). rowV Table row vertical padding (density knob): 14 comfortable (a 48 row) · 10 compact (a 40 row). barH The app bar's height (`--bar-h`, 64 comfortable · 56 compact) — the frame's one band, on the ground.

Surfaces 17

Everything the app is painted ON — the ground behind the content (the frame paints it too), the cards over it, the well inset in a card, and the washes that show state.

sur The GROUND (`--sur`): the app background, and the frame — the app bar and the rail paint it, with no fill, rule or shadow of their own. paper The CARD (`--paper`): tables, panes, charts, forms, sheets, menus — the plane every job sits on, a step above [sur]. paperW Sidebar / rail wash (`--paper-w`) — retiring with the rail wash (#892). well The WELL (`--well`): inset fills inside a card — photo plates, quote blocks, tracks, avatar blocks, neutral tags. ink4 State layer: hover wash, pressed, chip trays — opaque, over the card. cardEdge The card's hairline edge (`--card-edge`) — a LITERAL per theme, not an alias: in dark it is the card's RIM, its own value, because a shadow cannot lift a card off a near-black ground. cardSelEdge The selected record card's start-edge bar (`--card-sel-edge`): 0, or [edge] under [SelectionMark.edge]. surfaceEdge The frame a tile, sheet, panel or docked pane draws around itself (`--surface-edge`, aliasing `--card-edge` — every one a card now). hair Row + minor separators inside a card. hairS Structural: table header rule, sheet edges, a divider that must read. rowHover Table row hover wash. groundHover The state layer ON THE GROUND (`--ground-hover`, #892): the rail's hover, a ghost control on the bar. [ink4] is a CARD state layer and sits above the ground's value, so on the ground it vanishes; this steps the ground itself toward the ink — `color-mix(in srgb, var(--ink) 6%, var(--sur))`, derived in each factory from its own ink and ground, so the separation knob moves it with [sur]. groundGridInk The grid's line color (`--ground-grid`: the accent at 10%). groundGridSize The grid's pitch (`--ground-pattern-size`, 24). rowSel Table row selected wash. expandBg Expanded-row detail well. scrim Modal/sheet scrim.

Bands 10

The rail's head and the view bar beside it (one band across the top at 960 and wider), a pushed screen's bar, the compact bar and the compact nav bar — the band's fill, its rule, its hover and active faces, the resting field box on it, and the ink and accent control that sit on it. The rail's tree and its footer stay on the ground.

chrome A band's fill (`--chrome`): the app bar, the app band, the rail outside a drawer, the compact nav bar. chromeField A FIELD BOX's resting fill on a band (`--chrome-field`, #1186 — `AppBar.d.ts` ON A BAND): the search field resting on an accent or deep band takes this tonal step of the band — the on-chrome ink at 14% over [chrome] — with no border, and lift to [paper] while focused. Under [ChromeTone.ground] it is the field's ordinary paper fill, so nothing changes there. chromeHair A rule on a band (`--chrome-hair`). chromeHover A band's state layer (`--chrome-hover`). chromeSel The active nav item's face on a band (`--chrome-sel`). onChrome Text and glyphs on a band (`--on-chrome`). onChrome60 Secondary ink on a band (`--on-chrome-60`): meta, counts, borders. onChromeAccent An accent control on a band (`--on-chrome-accent`) — inverted under an accent or deep band (the #338 accent-on-accent cases). onChromeAccentInk The accent as INK on a band (`--on-chrome-accent-ink`, #1689): a lit glyph, an edge or a ring on the chrome. [accentInk] under a ground band; under an accent or deep band it inverts with the fill and IS [onChromeAccent]. [onChromeScope] maps [accentInk] onto it. onChromeOnAccent The ink on that control (`--on-chrome-on-accent`).

Text and controls 11

The ink ramp, the control outlines and the field's focus halo. Every pair the panel can break is watched by a contrast badge above.

ink Primary text. ink60 Secondary text. ink40 Tertiary: labels, counts, glyphs, placeholders — never body text. ink20 DIM MARKS, never text (`--ink20`): an unfilled priority bar, the grab bar, a stepped-back chart bar, the crosshair. btnBorder Default button outline. btnBorderHover Button outline on hover. fieldBorder A field's box (`--field-border`): text fields, selects, date fields, the combobox, the ref tile, the search field — the 3:1 boundary. chkBorder Checkbox border — the 3:1 boundary. focusHalo A FIELD's focus halo color (`--focus-halo`): the accent at 20%, derived from [accent] — the FILL, since a halo is a wash (#1689) — so a brand's halo follows its accent. focusHaloDanger A focused field IN ERROR (`--focus-halo-danger`, #896; `TextField.d.ts` THE FIELD STATES): [focusHalo]'s halo in the danger, the danger at 20%. edge Selection/cursor start-edge indicator width.

Status 7

The three voices that mean something — danger, caution and ok — each as a foreground and a surface wash, danger with a border as well.

danger Danger/error foreground — someone must act. dangerTint Danger/error surface wash — the filled tag and the banner a demanding status takes. dangerEdge Danger/error border. caution The caution ink (`--caution`, #922): the StatusPill caution plate's word and the chart tier's caution tone (a donut segment, a gauge band, an aging segment). ONE number on both kits — the token's oklch value converted, never a color this kit derives. Accent-independent. cautionTint The caution plate's wash (`--caution-tint`) — [caution] at the token's alpha, so the plate composites on whatever surface it sits on. ok Success/resolved foreground — the estate's one green (`--ok`). Accent-independent like [danger]; appears only where resolution or success is stated (StatusPill positive, resolved chips), never as a third decorative voice. okTint Success/resolved surface wash (`--ok-tint`).

Data 5

The default pin head, its glyph and its halo, and the group bands. A pin's category color comes from the palette, named in the theme seed.

pinFill The head of a pin that names neither a category nor a status (`--pin-fill: var(--accent)`; `MapView.d.ts` ONE CHANNEL PER JOB). It IS the themed accent by definition. pinFg The glyph on [pinFill] (`--pin-fg: var(--on-accent)`); a palette fill takes its own [KitPaletteColor.on]. pinHalo The 1.5px ring OUTSIDE a pin head's rim, so any fill reads on any basemap (`--pin-halo`: the paper at 85%; `MapView.d.ts` EVERY FILL IS LEGIBLE ON EVERY BASEMAP). group0 Level-0 group header band. group1 Level-1 group header band.

Map 11

The basemap's roles — land, water, parks, roads and their casings, buildings, labels — and the pending pin's gray. A raster basemap keeps its own imagery; these paint the map's plate and any kit-drawn map.

mapLand Land — the map's plate (`--map-land`). mapWater Water (`--map-water`). mapPark Parks and green space (`--map-park`). mapRoad A minor road's fill (`--map-road`). mapRoadEdge A minor road's casing (`--map-road-edge`). mapRoadMajor A major road's fill (`--map-road-major`). mapRoadMajorEdge A major road's casing (`--map-road-major-edge`). mapBuilding Building footprints (`--map-building`). mapLabel Place and road labels (`--map-label`). mapLabelWater Water labels (`--map-label-water`). pinPending A PENDING pin's head (`--pin-pending`, #894): the StatusMark `pending` tone on a pin with no category, whose fill says its status — and the hollow status badge's border beside one (`MapView.d.ts` ONE CHANNEL PER JOB, #972). [accent], [ok] and [danger] carry the other three. Clears 3:1 on [mapLand]; never text.

Scrollbars 6

Every scroller's bar: the thumb at rest and while hovered or dragged, the strip it rides, and the desk bar's thickness, side gap and corners. The desk half shows only while a fine pointer is attached; at touch the platform's own overlay keeps its size.

scrollbarThumb The scrollbar thumb at rest (`--scrollbar-thumb`, aliasing [ink40]): the muted-ink role, which clears the 3:1 a draggable control needs on [sur] and [paper] — never the state layer, which Material's Android thumb reads by default and which cannot be seen on [sur]. scrollbarThumbHover The thumb while hovered or dragged (`--scrollbar-thumb-hover`, aliasing [ink60]) — one ink level up; the thumb never grows. scrollbarTrack The strip the thumb rides (`--scrollbar-track`): transparent in graphite, so the thumb reads against the surface it scrolls. A theme may fill it. scrollbarSize The DESK scrollbar thumb's thickness (`--scrollbar-size`, 8). Applied only while a fine pointer is attached; at touch the platform's overlay keeps its own. scrollbarInset The clear gap on either side of the desk thumb (`--scrollbar-inset`, 2) — `ScrollbarThemeData.crossAxisMargin` — so a scroller's bar takes [scrollbarSize] + 2 × this. scrollbarRadius The thumb's corner radius (`--scrollbar-radius`, aliasing [rS]): the control radius, so a theme that moves [rS] moves its thumbs with no widget edit.

Advanced 6

Real controls that are not decisions — motion durations, the focus ring offset, the touch floor. Opens collapsed on purpose.

tQuick Quick transition duration — chevrons, hovers, checks. tMove Move transition duration — sheets, rail, menus. tDraw Draw transition duration (`--t-draw`) — the chart entrance band, the draw-in choreography's clock. tStagger Per-mark entrance offset (`--t-stagger`) — the delay each successive mark takes on top of the entrance band; the per-mark offset clamps at 20 steps, so a large series never trails past the band. focusOffset Focus ring offset. touch Minimum hit-target floor. Follows the POINTER, not the density knob alone (rhythm.css): 44 at comfortable (touch surfaces — never shrink below on touch), 32 at compact, which only ever applies with a fine pointer attached. Density-resolving this is what lets the control set — and a control-bearing table row — densify together (V-16).
