# wxColourDatabase Class Reference
[Graphics Device Interface (GDI)]

`#include <wx/gdicmn.h>`

## 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 | MEDIUM FOREST GREEN MEDIUM GOLDENROD MEDIUM ORCHID MEDIUM SEA GREEN MEDIUM SLATE BLUE MEDIUM SPRING GREEN MEDIUM TURQUOISE MEDIUM VIOLET RED MIDNIGHT BLUE NAVY ORANGE ORANGE RED ORCHID PALE GREEN PINK PLUM PURPLE | RED SALMON SEA GREEN SIENNA SKY BLUE SLATE BLUE SPRING GREEN STEEL BLUE TAN THISTLE TURQUOISE VIOLET VIOLET RED WHEAT WHITE YELLOW YELLOW GREEN
