Great UX starts with two basic principles - ease of use and simplicity. Selecting a color should be as easy as moving a slider, clicking a checkbox or pressing a key just like other basic form elements behave.
This is a flexible and minimalistic color picker. Developed with mobile devices and keyboard usage in mind. Key features:
The right color picker, but not the framework you're looking for?
Color Picker on npm
npm install @radial-color-picker/react-color-picker
And in your app:
import ColorPicker from '@radial-color-picker/react-color-picker';
import '@radial-color-picker/react-color-picker/dist/style.css';
function App() {
const [color, setColor] = useState({
hue: 90,
saturation: 100,
luminosity: 50,
alpha: 1,
});
const onInput = (hue) => {
setColor((prev) => ({ ...prev, hue }));
};
return <ColorPicker {...color} onInput={onInput} />;
}
Depending on your build tool of choice (vite, webpack, etc.) you may have to setup the appropriate plugins or loaders. If you're using vite you don't have to do anything else - it comes preconfigured and supports CSS import out of the box.
ColorPicker can be used either as a controlled component or as uncontrolled component.
// Controlled component. Its current state is defined and updated by the props you pass to it.
<ColorPicker hue={value} onInput={(hue) => setValue(hue)} />
// Uncontrolled component. You can use onChange to react to knob rotation stop for example.
<ColorPicker onChange={(hue) => console.log('Current color:', hue)} /> Name Type Default Description hue Number 0 A number between 0-359. saturation Number 100 A number between 0-100 luminosity Number 50 A number between 0-100 alpha Number 1 A number between 0-1 disabled Boolean false A boolean to disable UI interactions step Number 2 Amount of degrees to rotate the picker with keyboard and/or wheel. variant String collapsible Use persistent to prevent collapsing/closing initiallyCollapsed Boolean false Hides the palette initially mouseScroll Boolean false Use wheel (scroll) event to rotate. ariaLabelColorWell String color well Labels the color well onInput Function noop Called every time the color updates. Use this to update the hue prop. onChange Function noop Called every time the color changes, but unlike onInput this is not called while rotating the knob. onSelect Function noop Called when the user dismisses the color picker (i.e. interacting with the middle color well). What's the browser support?
The last two versions of major browsers (Chrome, Safari, Firefox, Edge) are supported though it will probably work in other browsers, webviews and runtimes as well.
How to select other shades of the solid colors?We suggest to add a custom slider for saturation and luminosity or use <input type="range">.
onInput/onChange events?
Event names are based on the HTML <input type="color">. MDN: As is the case with other <input> types, there are two events that can be used to detect changes to the color value: input and change. input is fired on the <input> element every time the color changes. The change event is fired when the user dismisses the color picker.
It's another non-passive event that could potentially introduce jank on scroll. To rotate the color knob, but stay on the same scrolling position the wheel event is blocked with preventDefault(). Thus, if you really want this feature for your users you'll have to explicitly add mouseScroll={true}.
Please see Releases for more information on what has changed recently.
dist directory has been renamed from react-color-picker.min.css to style.css.Double-click to move the knob to the current position of the pointer is gone since this is now the default behavior as soon as the clicks on the palette. If you had a tooltip or a help section in your app that described the shortcut you should remove it.
With v3 the keyboard shortcuts are better aligned with the suggested keys for any sliders. This means that the Shift/Ctrl + ↑/→/Shift/Ctrl + ↓/← non-standard key combos are replaced by the simpler PageDown and PageUp. If you had a tooltip or a help section in your app that described the shortcut keys you should update it.
The onChange event is now emitted when the user changes the color (knob drop, click on the palette, keyboard interaction, scroll) and a onSelect event is emitted when interacting with the color well (middle selector).
<ColorPicker
hue={hue}
onInput={updateHue}
- onChange={onColorSelect}
/>
<ColorPicker
hue={hue}
onInput={updateHue}
+ onChange={onColorChange}
+ onSelect={onColorSelect}
/>
v2 comes with lots of performance improvements like native CSS conic-gradient support and lots of bugfixes, but some things were changed as well.
- import '@radial-color-picker/react-color-picker/dist/react-color-picker.umd.min.css'; + import '@radial-color-picker/react-color-picker/dist/react-color-picker.min.css';
onChange prop is called onInput and onSelect prop is called onChange now. The reason for that is to align with the event names on the HTML <input type="color">.- <ColorPicker {...color} onChange={onHueChange} onSelect={onMiddleSelectorClick} />
+ <ColorPicker {...color} onInput={onHueChange} onChange={onMiddleSelectorClick} />
onInput and onChange props were streamlined and will no longer pass the saturation, luminosity and alpha props back. Instead hue will be the only param. This reduces unneeded object creation and in certain edge-cases skips unneeded re-renders (comparing two numbers vs. two objects).- const onHueChange = (color) => {
- setHue(color.hue);
- };
+ const onHueChange = (hue) => {
+ setHue(hue);
+ };
