- bb:select-color COLOR #!optional STRINGprocedure
Pops up a color-selection dialog. If COLOR is an exact integer, or a symbol naming one of the default colors, then the user can select a color index, which will then be returned. If COLOR is a three-element list or vector, then the user can select an RGB (or HSV) color. bb:select-color either returns a color value (an integer, encoding a color index or a packed RGB value), or #f if the selection dialog was closed or canceled.
