ColorPicker API#

Run this demo live in your browser ▶

ColorPicker wraps the browser's native color input and syncs the chosen #RRGGBB value back to Python as color, with an rgb property that hands you the three channels as integers. Reach for it when a plot color, a brush color or a mask tint is easier to choose by eye than to type as a literal; show_label controls whether the hex string is printed next to the swatch.

See also: Paint for a canvas with the same picker built into its toolbar, CopyToClipboard for handing the resulting hex string to someone else, and TangleSlider for the same by-eye approach to numbers.
