Definition of some RGB colors and color conversion functions
Convert a color to an OpenGL RGB color.
The output is a tuple of three RGB float values ranging from 0.0 to 1.0. The input can be any of the following: - a QColor - a string specifying the Xwindow name of the color - a hex string ‘#RGB’ with 1 to 4 hexadecimal digits per color - a tuple or list of 3 integer values in the range 0..255 - a tuple or list of 3 float values in the range 0.0..1.0 Any other input may give unpredictable results.
Return a string designation for the color.
color can be anything that is accepted by GLColor. In most cases If color can not be converted, None is returned.
