A new globals.css built on the shadcn defaults. Override the colors you care about below — the rest is derived.

Reads any :root block, top-level or in @layer base. Only the colors you change are rewritten — comments, formatting, and untouched .dark values are preserved exactly.

Recalculate text colors. Change a surface like --primary and its foreground is rewritten to clear 4.5:1 contrast.Writes back in oklch() · hsl() · rgb() · hex

Core colors

Primary*

Light

Dark

Primary buttons, links, and active states.

Secondary*

Light

Dark

Secondary buttons and subdued UI surfaces.

Accent*

Light

Dark

Highlighted/hover surfaces and accent UI elements.

Charts

Chart color

Light

Dark

Base color for the 5-step chart scale. Starts at whatever --chart-1 is; change it and all five (--chart-1 through --chart-5) are regenerated.

Matches AccentEnter a color to set it separately.

Surfaces

Background

Light

Dark

Page background color.

Foreground (Text)

Light

Dark

Text sitting directly on the page background — headings, paragraphs, sheet/dialog titles, and outline/ghost button labels. Cards and popovers use their own foreground instead.

Card

Light

Dark

Card surface background color.

Popover

Light

Dark

Popover/dropdown surface background color.

Muted

Light

Dark

Subtle background fills, e.g. disabled states.

Border

Light

Dark

Default border color for cards, dividers, table rows, and outline buttons. Form inputs use Input border instead.

Form Inputs & Feedback

Input border

Light

Dark

Outlines inputs, textareas, selects, checkboxes and radios. The fields themselves are transparent, taking their fill from whatever surface they sit on, so this is their edge and not their background. It does fill one thing: a toggle switch in its off position.

Focused input border

Light

Dark

Replaces the border, plus a soft glow, on whatever has keyboard focus — inputs and selects, but also buttons, tabs and sliders.

Destructive

Light

Dark

Destructive actions like delete buttons and error states.
