Allocate a color

Allocates a read-only colormap entry corresponding to the closest RGB value supported by the hardware. If you are using TrueColor, you can take a shortcut and directly calculate the color pixel value to avoid the round trip. But, for example, on 16-bit color setups (VNC), you can easily get the closest supported RGB value to the RGB value you are specifying.

parameters:

• c: The connection object to the server

• cmap: TODO

• red: The red value of your color.

• green: The green value of your color.

• blue: The blue value of your color.
