Anatomy

Parts are authored in your own markup and identified by the selector below, so your CSS can target the same anatomy without loading Timeless styles. Required parts must be present for the component to work. Private data-ui-internal-* hooks are written by the runtime and must never be authored.

Part	Required	Selector	Purpose
`preview`	No	`[data-ui-part~='preview']`	Region holding the format select, gamut controls, and readout.
`preview-bar`	No	`[data-ui-part~='preview-bar']`	Row above the readout.
`format-field`	No	`[data-ui-part~='format-field']`	Label wrapper around the format select.
`format`	Yes	`select`	Native `<select>` listing the supported color formats.
`gamut-bar`	No	`[data-ui-part~='gamut-bar']`	Row holding the clamp buttons.
`clamp`	No	`[data-ui-part~='clamp']`	Button that clamps an out-of-gamut color into sRGB or P3. Shown only when needed.
`readout`	No	`[data-ui-part~='readout']`	Row holding the swatch, raw input, and copy button.
`gamut`	No	`[data-ui-part~='gamut']`	Current-color swatch. Decorative.
`input`	Yes	`input[type='text']`	Raw CSS color value, editable as text.
`input-label`	No	`[data-ui-part~='input-label']`	Screen-reader label for the raw input or format select.
`copy`	No	`[data-ui-part~='copy']`	Copies the raw value to the clipboard.
`copy-icon`	No	`[data-ui-part~='copy-icon']`	Idle state of the copy button. Decorative.
`copied-icon`	No	`[data-ui-part~='copied-icon']`	Confirmed state of the copy button. Decorative.
`channels`	No	`[data-ui-part~='channels']`	Container for the per-channel rows.
`channel`	Yes	`[data-ui-part~='channel']`	One channel row. The picker rewrites the rows when `format` changes, so author one row per channel of the widest format you support.
`channel-label`	No	`[data-ui-part~='channel-label']`	Channel name. Written by the picker; decorative.
`channel-range`	Yes	`input[type='range']`	Slider for one channel.
`channel-input`	Yes	`input[type='number']`	Numeric entry for one channel.
`warning`	No	`[data-ui-part~='warning']`	Out-of-gamut or unparsable-value message.
`trigger`	No	`[data-ui-part~='trigger']`	Optional button when the picker lives inside a popover.
`content`	No	`[data-ui-part~='content']`	Optional popover surface wrapping the picker.

Attributes

Every value below is implemented by the stylesheets this component ships. Boolean attributes are presence-based: author the attribute with no value, or omit it.

Attribute	Values	Default	Description
`format`	`oklch` · `oklab` · `lch` · `lab` · `hex` · `rgb` · `hsl` · `hwb` · `p3` · `rec2020`	`oklch`	Color space the channel controls edit and the raw input round-trips through. The picker converts the current value when this changes.
`value`	any `string`	—	Initial and form-reset color, in any CSS color syntax. Unlike the collection elements, the picker reflects one `value` property rather than a separate authored default.

Element API

Attributes above are the authoring surface. These are the DOM properties and events the registered element adds once it upgrades.

`<ui-color-picker>`

Property	Type	Notes
`format`	`'oklch' \| 'oklab' \| 'lch' \| 'lab' \| 'hex' \| 'rgb' \| 'hsl' \| 'hwb' \| 'p3' \| 'rec2020'`	Reflects the `format` attribute, documented above.
`value`	`string`	Reflects the `value` attribute, documented above.

Event	Detail	Description
`input`	`Event`	Native `input` event dispatched while the color is being edited.
`change`	`Event`	Native `change` event dispatched when the edit is committed.

Styling

Root identity: ui-color-picker. Required stylesheets: tokens.css, color-picker.css.

This component adds no custom properties of its own. Restyle it through the design tokens or your own CSS.

Design tokens this component reads (24)

These are global Atmosphere tokens. Change them once at the theme level rather than per component.

--ui-bg-control · --ui-bg-surface · --ui-bg-surface-raised · --ui-bg-surface-subtle · --ui-checkerboard · --ui-danger · --ui-disabled-opacity · --ui-fg · --ui-fg-muted · --ui-focus · --ui-font-mono · --ui-line · --ui-line-strong · --ui-radius-lg · --ui-radius-md · --ui-radius-pill · --ui-radius-sm · --ui-shadow-control · --ui-shadow-floating · --ui-space-2 · --ui-space-3 · --ui-space-4 · --ui-warning · --ui-warning-soft

Accessibility

Keep the native elements, roles, and relationships shown in the example. Timeless adds only the state and keyboard coordination the platform does not already provide, and it never supplies your accessible names — those depend on your content.

Before JavaScript runs

The markup above is complete and usable on its own: native controls submit, labels associate, and authored ARIA is already correct. Registration adds state synchronisation, focus management, and keyboard coordination on top of it.
