Tincture

# Tincture

## Philosophy

A dark colour-reading vault where every saturated hue is a measured specimen bound to one named product role, shown as a suspended glass vial over ink-charcoal; colour is data, never decoration.

### Values

- colour as measured data
- one reading, one bound role
- dark architectural calm
- material depth without borders
- handmade pigment intelligence

### Anti-Values

- colour as decoration
- rainbow confetti and sprays
- bright generic product console
- neon glow
- muddy washes
- textbook colour-wheel layouts

### Radii

- **None**: 0
- **Sm**: 16px
- **Md**: 16px
- **Lg**: 24px
- **Full**: 9999px

### Shadows

- **Sm**: 0 1px 2px rgba(0,0,0,0.5)
- **Md**: 0 18px 44px rgba(0,0,0,0.55)
- **Lg**: 0 40px 90px rgba(0,0,0,0.6)

### Spacing

- **Base**: 8px
- **Scale**: [4,8,12,16,24,32,48,64]

### Surfaces

- **Treatment**: translucent frosted glass on a deep ink-charcoal vault: low-alpha white linear gradient, backdrop blur, and an inset top highlight
- **Card Style**: frosted glass pane, radius 24, soft dark shadow, inset top highlight, no border; an optional spectral-seam segment when it divides bound readings
- **Bg Pattern**: near-black ink-charcoal with one faint violet light-well from the specimen, never decorative confetti

### Borders

- **Default Width**: 0
- **Accent Width**: 0
- **Style**: no borders; depth comes from frosted material, soft shadow, and an inset white-12% highlight
- **Character**: colour appears only as a bound reading on a vial, gauge, role dot, or badge; never as a decorative card edge

### Motion

- **Duration**: 200ms
- **Easing**: cubic-bezier(0.2, 0.8, 0.2, 1)
- **Philosophy**: a short rise-and-settle on scroll and a colour-wash focus ring; the settled state is the default, fully visible with no JavaScript; motion is layered on only when JS sets js-anim; respects prefers-reduced-motion

## Rules

### Composition

A centred stage with a thin luminous spectral seam pinned to the far left holding the bound readings; content flows as a single calm column of frosted glass panes over an ink-charcoal vault. The dashboard adds a breathing left index, never a boxed widget.

### Hierarchy

Typography (Fraunces serif display vs Space Grotesk body vs mono metadata), glass elevation, and the spectral seam create hierarchy; saturated colour is reserved for bound readings, states, and alerts only.

### Density

Instrument-readout rhythm: compact mono metadata and controls inside airy frosted panes, with visible coordinate and deltaE values for a trusted measurement tool.

### Signature

Suspended vial readings on the spectral seam — each pigment is a glass vial filled to a measured level over the dark vault, labelled with its hex coordinate and the single product role it owns; the bound set stacks into one continuous master strip.

## Layout

### Grid

Centred stage: a ~64px spectral-seam gutter on the left and a fluid single column of glass panes; the dashboard uses an 18px seam + 240px breathing index + fluid main.

### Whitespace

Dark and architectural — generous outer gutters, tight internal control spacing, no loose decorative gaps; the ink ground carries the negative space.

### Density

Compact mono metadata inside airy frosted sections; values, coordinates, and deltaE always shown.

### Responsive

Below 820px the spectral seam and side index collapse, the top nav hides non-essential links, grids fold to a single column with minmax(0,1fr); only the landing hero spans full-bleed.

### Breakpoints

- **Mobile**: 390px
- **Tablet**: 768px
- **Desktop**: 1440px
- **Ultrawide**: 2560px

## Guidance

### Do

- Bind every saturated colour to one named product role and keep the mapping fixed.
- Show colour as a measured vial with its hex coordinate, not as a bare swatch grid.
- Keep the field deep ink-charcoal and quiet so a single reading can lead.
- Build elevation from frosted material and soft shadow, never from borders.
- Pair role colour with a text label or pill, never colour alone.

### Don't

- Do not spray colour as confetti or give a pane a decorative accent edge with no role.
- Do not add borders, neon glow, or muddy washes.
- Do not let semantic red or amber become visually primary.
- Do not default to a bright silver product console; the dark vault is the identity.
- Do not bury hero subjects so the veil erases them.

### Accessibility

Light ink #ECEFF2 on the ink-charcoal vault and charcoal on saturated readings clear WCAG AA; focus is a visible violet ring plus a soft wash; role colour is always paired with a label, value, or pill; the settled page renders with no JavaScript; respects prefers-reduced-motion.

## Imagery Direction

### Pairs With

frostmark

### Summary

A single luminous pigment specimen — a slender glass vial of glowing concentrated tincture — suspended in a near-black vault, veiled behind layered frosted glass slabs with hairline seams; gouache daubs crest the glass edges as measured colour samples.

### Subjects

- a glowing pigment vial / colour specimen
- a measured swatch suspended in shadow
- a master colour strip read against the dark
- a single luminous reading

### Usage

Full-bleed dark hero with negative space at top for a centred-low headline overlay; charcoal-to-near-black tonal depth; daubs few and placed, never confetti.

## shadcn/ui Usage

When the target app uses shadcn/ui, copy DESIGN.md with shadcn instead of the plain DESIGN.md. It contains the same Katagami design-language source plus the shadcn/ui primitives, imports, theme variables, component recipes, and preview-shot guidance.

DESIGN.md with shadcn: `/language/en-019efa8b-fedc-7b53-b645-a940c514ea6b/DESIGN.with-shadcn.md`.

The shadcn page also exposes optional machine-readable files for automation, but the human-facing handoff is DESIGN.md with shadcn.

Install recommended primitives with `npx shadcn@latest add button card input textarea select dialog sheet tabs badge separator checkbox switch slider tooltip dropdown-menu table`.

Use these primitives in shadcn apps:
- button
- card
- input
- textarea
- select
- dialog
- sheet
- tabs
- badge
- separator
- checkbox
- switch
- slider
- tooltip
- dropdown-menu
- table

Implementation rule for agents: import shadcn primitives from `@/components/ui/*`, apply the generated CSS variables first, then compose the language-specific recipes from the companion MD. Katagami remains the source of truth; shadcn names are the implementation surface.

## Do's and Don'ts

- Do Bind every saturated colour to one named product role and keep the mapping fixed.
- Do Show colour as a measured vial with its hex coordinate, not as a bare swatch grid.
- Do Keep the field deep ink-charcoal and quiet so a single reading can lead.
- Do Build elevation from frosted material and soft shadow, never from borders.
- Do Pair role colour with a text label or pill, never colour alone.
- Don't Do not spray colour as confetti or give a pane a decorative accent edge with no role.
- Don't Do not add borders, neon glow, or muddy washes.
- Don't Do not let semantic red or amber become visually primary.
- Don't Do not default to a bright silver product console; the dark vault is the identity.
- Don't Do not bury hero subjects so the veil erases them.

### Accessibility

Light ink #ECEFF2 on the ink-charcoal vault and charcoal on saturated readings clear WCAG AA; focus is a visible violet ring plus a soft wash; role colour is always paired with a label, value, or pill; the settled page renders with no JavaScript; respects prefers-reduced-motion.
