Detailed Description

wxWidgets maintains a database of standard RGB colours for a predefined set of named colours.

The application may add to this set if desired by using AddColour() and may use it to look up colours by names using Find() or find the names for the standard colour using FindName().

There is one predefined, global instance of this class called wxTheColourDatabase.

The standard database contains at least the following colours:

AQUAMARINE BLACK BLUE BLUE VIOLET BROWN CADET BLUE CORAL CORNFLOWER BLUE CYAN DARK GREY DARK GREEN DARK OLIVE GREEN DARK ORCHID DARK SLATE BLUE DARK SLATE GREY DARK TURQUOISE DIM GREY

FIREBRICK FOREST GREEN GOLD GOLDENROD GREY GREEN GREEN YELLOW INDIAN RED KHAKI LIGHT BLUE LIGHT GREY LIGHT STEEL BLUE LIME GREEN MAGENTA MAROON MEDIUM AQUAMARINE MEDIUM BLUE
