A colour picker is the most intuitive way to select a colour and read its numeric value — particularly when you know what you want visually but not its code. This picker provides a full HSL wheel with saturation/lightness selection and outputs the picked colour as HEX, RGB, HSL, HSV, and CMYK simultaneously.
The outer ring selects the hue (0–360°). The inner square sets saturation (left–right) and lightness (top–bottom). Moving around the square changes the colour while maintaining the chosen hue. The opacity slider adds an alpha channel. All representations update in real time as you drag. You can also type values into any field and the picker will jump to the corresponding colour.
A colour picker starts with a visual selection — drag to choose a colour by sight. A converter starts with a numeric value in one format and translates it to others. Use the picker when you know how a colour looks; use the converter when you know its code.
Named CSS colour keywords are supported in the input field. Try typing "orange", "cornflowerblue", or any CSS named colour — the picker will jump to that colour and show its numeric equivalents.
Modern browsers support the EyeDropper API. Click the eyedropper icon (if shown) to pick any colour visible on your screen. Chrome supports this from version 95; Firefox support varies.
6-digit HEX is #rrggbb for opaque colours. 8-digit HEX is #rrggbbaa where the last two digits are the alpha channel (00 = transparent, FF = opaque). CSS supports 8-digit HEX in all modern browsers.
