int makecol32(int r, int g, int b);

These functions convert colors from a hardware independent form (red,  green, and blue values ranging 0-255) into various display dependent  pixel formats. Converting to 15, 16, 24, or 32-bit formats only takes a  few shifts, so it is fairly efficient. Converting to an 8-bit color  involves searching the palette to find the closest match, which is quite  slow unless you have set up an RGB mapping table (see below). Example:

   /* 16 bit color version of green. */
   int green_color = makecol16(0, 255, 0);

Returns the requested RGB triplet in the specified color depth.
