The unit SDLColors contains a collection of basic declarations, procedures and functions for manipulating colors. Amongst these routines are conversion functions for HSI (hue, saturation, intensity) and RGB (red, green, blue) color systems. Further, the unit SDLColors contains the class TColorArray which supports the handling of color arrays.

More details can be found in the online help pages.
