ColorSwatch

A static preview box rendering one color value as a filled, shaped swatch, backed by a fixed checkerboard so a translucent value always reads correctly against whatever sits behind it on the page rather than blending invisibly away.

Installation

An ordinary dependency: install it, import the theme once, and import the component where it is used.

npm add @sdxc/ui

import "@sdxc/ui/theme.css";

Usage

import { ColorSwatch } from "@sdxc/ui";

Renders a fixed-size <span> that paints value through a local --ui-color-swatch-value custom property, layered over a ::before checkerboard so any transparency in value reads correctly.

Examples

<ColorSwatch value="rgb(16 185 129 / 0.4)" shape="circle" size="lg" />

Props

Read from the component's own types, so every prop, every default and every allowed value is listed.

Prop	Type	Description
`value`	`string`	The color to preview, already resolved to a literal CSS value — a hex string, `rgb()`/`hsl()`/`oklch()` function, or named color. Required, since a swatch with nothing to preview has no reason to render.
`shape?`	`"circle" \| "square" \| "rounded"`	Shape variant. Defaults to DEFAULT_SHAPE.
`size?`	`"sm" \| "md" \| "lg"`	Size variant. Defaults to DEFAULT_SIZE.

Also accepts everything in TagProps<"span">.

Types

Name	Values	What it decides
`Shape`	`"circle" \| "square" \| "rounded"`	Shape variant controlling the swatch's corner rounding: `"circle"` renders a fully rounded disc, `"square"` renders sharp corners, and `"rounded"` renders a softly rounded square.
`Size`	`"sm" \| "md" \| "lg"`	Size variant controlling the swatch's rendered dimensions.
