Hello to you all.

I know how to manipulate hex colours by splitting the num bers up and perfoming calcutaions on them using bit-operators. Thats fine…

but i now need to manipulate colour not using the normal RGB. I need to be able to add two colours together like paint. E.g. red and blue equals purple, yellow and blue equals green.

Has anyon e had any experience with this and even more importantly can it be done? (i assume it can… nothings impossible)

cheers

James
