Howdy all,

This may actually be more of a maths question so move it if need be. I'm wanting to know if anyone could provide me with an example of comparing two color values, at high speed. For example, say I have a Color Table, which has 20 colors in it. I want to get the value of a color, and check it against this table. If it comes close to another color in the table within a certain margin of error, then just change that color to the one in the table. If it doesn't, keep its color and add it to the table.

I'm stumped as to how I would go about this, so any suggestions would be nice

TIA,

chem
