Usage

usage.tsx
import { ColorSwatch } from "@/components/ui/color-swatch";export function Example() {  return <ColorSwatch color="oklch(0.65 0.2 250)" aria-label="Blue" />;}
  • Display a selected color in color pickers, palettes, or form controls.
  • Show color values in design-token lists, theme editors, and visual configuration panels.
  • Represent transparent or partially opaque colors while preserving their alpha preview.
  • Use asChild when the swatch needs to merge with another element or custom component.

Examples

Solid color

Render a standard color preview.

solid-color.tsx
import { ColorSwatch } from "@/components/ui/color-swatch";export function SolidSwatch() {  return <ColorSwatch color="#7c3aed" size="default" />;}

Transparent color

Render an alpha color over the built-in checkerboard background.

transparent-color.tsx
import { ColorSwatch } from "@/components/ui/color-swatch";export function AlphaSwatch() {  return <ColorSwatch color="rgb(59 130 246 / 50%)" size="lg" />;}

Empty color state

Show the built-in no-color indicator.

empty-color-state.tsx
import { ColorSwatch } from "@/components/ui/color-swatch";export function EmptySwatch() {  return <ColorSwatch color="" size="sm" />;}

Disabled swatch

Expose disabled state through data-disabled and aria-disabled attributes.

disabled-swatch.tsx
import { ColorSwatch } from "@/components/ui/color-swatch";export function DisabledSwatch() {  return <ColorSwatch color="#16a34a" disabled />;}

API reference

PropTypeDefaultDescription
colorstringundefinedOptional CSS color value. Whitespace is trimmed. Valid solid colors use backgroundColor; valid colors with detected alpha use a checkerboard transparency preview unless withoutTransparency is true. Missing or empty values show a diagonal no-color indicator.
size"default" | "sm" | "lg" | null | undefined"default"Controls the swatch size: default is 2rem, sm is 1.5rem, and lg is 3rem.
asChildbooleanfalseWhen true, renders through Radix Slot so the swatch props and styling are applied to its child element instead of a div.
disabledbooleanfalseSets aria-disabled and the data-disabled attribute. The default styles disable pointer events and reduce opacity.
withoutTransparencybooleanfalseWhen true, suppresses the checkerboard alpha preview and renders a valid color using backgroundColor.
classNamestringundefinedAdditional classes merged with the generated size and base classes.
styleReact.CSSPropertiesundefinedAdditional inline styles merged after the generated background styles. User-provided style values override generated values when they overlap.
HTML div propsReact.ComponentProps<"div"> excluding childrennullAll standard div attributes supported by React, including id, role-related attributes, data attributes, event handlers, and aria attributes. The children prop is explicitly omitted because the component is self-closing.

Accessibility

  • The component always uses role="img".
  • The aria-label is automatically "No color selected" when color is empty or missing, otherwise it is "Color swatch: {trimmed color}".
  • The disabled prop adds aria-disabled="true" and data-disabled, but it does not create native button or form-control behavior.
  • When using asChild, ensure the child element can accept the rendered ARIA, data, className, style, and event-handler props.
  • A custom aria-label passed through props is spread before the component's generated aria-label, so the generated label takes precedence; use the color value or surrounding context accordingly.
