Color picker
A control for choosing a color visually.
A color picker is a specialized input that opens a panel of colors instead of asking the user to type a hex code. Most pickers offer a 2D area for hue and brightness plus a slider for saturation, and often a hex input as a fallback.
For everyday users, a small palette of preset colors is friendlier than a full picker. Save the full picker for power users (designers, themers) who really do need exact control.
