Description:
CL_Palette represents a palette in the form of a 256 byte array.
Palettes are in ClanLib only used by surface providers. A provider specifies it's palette by returning a CL_Palette. But It can also choose to return NULL. In that case it will use the system palette. You can change the system palette from CL_Display or CL_DisplayCard.
