Determing RGB values

Question:
Is there an easy way of determining the RGB values when you have the long value of a color (for example, a "reverse" RGB(x,y,z) function)?

Answer:
You can make use of the Mod function to convert a long back into its Red, Green and Blue values. For example:


li_Red = int( mod( ll_LongCol, 256 ) )
li_Green = int( mod( ll_LongCol / 256, 256 ) )
li_Blue = ll_LongCol / ( 256 * 256 )
