All The Colors

Use to open an interactive color picker widget when the user needs a concrete color value chosen or adjusted. The tool accepts an optional starting color and optional suggested color swatches, then lets the user visually and numerically refine the result (hue, saturation, lightness/value, transparency, and exact hex/RGB) and returns the selected color. Invoke this for color design actions such as showing a named/hex color, warming or cooling a color, lightening or darkening it, desaturating or muting it, or selecting a complementary color for a palette. Do not invoke this for questions that are only about color meaning, etymology, or cultural context without a color-picking outcome.
