Gdk::Color is used to describe an allocated or unallocated color.
It contains the following data: pixel: For allocated colors, the value used to draw this color on the screen. red: The red component of the color. This is a value between 0 and 65535, with 65535 indicating full intensitiy. green: The green component of the color. blue: The blue component of the color.
