Theme Tokens And Examples

Token Families

Surface

Token	Usage
`surface.background`	Main app background
`surface.elevated`	Inputs, cards, panels, popovers
`surface.muted`	Secondary backgrounds and sidebars
`surface.foreground`	Primary text
`surface.mutedForeground`	Secondary text and hints
`surface.subtle`	Subtle dividers

Interactive

Token	Usage
`interactive.border`	Default borders
`interactive.hover`	Hover on clickable elements only
`interactive.active`	Pressed interaction state
`interactive.selection`	Active/selected items
`interactive.selectionForeground`	Text on selection
`interactive.focusRing`	Focus indicators

Status

Use status colors only for actual feedback.

status.error: errors and validation failures
status.warning: cautions
status.success: successful outcomes
status.info: informational feedback

Each family may expose foreground, background, and border variants.

Primary

primary.base: primary CTA
primary.hover: primary hover
primary.foreground: content on primary

Primary means “act”; selection means “currently active.” Do not use primary to mark ordinary selected tabs or rows.

Syntax

Use syntax.* only for code display: code backgrounds/text, keywords, strings, and diff highlights. Never use syntax colors for ordinary UI chrome.

Usage

Prefer semantic utility classes when available:

<div className="bg-[var(--surface-elevated)] text-foreground" />
<button className="hover:bg-interactive-hover" />

Use useThemeSystem() when a library/API requires actual color values:

const { currentTheme } = useThemeSystem();

<Chart color={currentTheme.colors.status.error} />

Common Patterns

Input Area

<div className="bg-[var(--surface-elevated)]">
  <textarea className="bg-transparent" />
  <div className="bg-transparent">...</div>
</div>

Input footers stay transparent over the elevated input surface.

Active Item

<button className={isActive
  ? 'bg-interactive-selection text-interactive-selection-foreground'
  : 'hover:bg-interactive-hover'
} />

Error Feedback

<div className="bg-[var(--status-error-background)] text-[var(--status-error-foreground)]" />

Neutral Card

<section className="bg-[var(--surface-elevated)] text-foreground">
  <p className="text-muted-foreground">...</p>
</section>

Wrong Patterns

<div style={{ backgroundColor: '#F2F0E5' }} />
<button className="bg-blue-500" />
<div className="hover:bg-interactive-hover">Static content</div>
<Tab className="bg-primary">Active</Tab>

Use theme tokens, apply hover only to interactive elements, and distinguish selection from primary actions.
