    question about color blending

    Hi, I love ArtRage2! I recently bought the full version and it actually inspired me to go buy a Wacom Graphire4 tablet, and prior to this I wasn't even into art type activities at all. I'm having a lot of fun.

    A small question though.. when i mix red and blue with the palette knife, i get purple. Red and yellow, I get orange. When I mix blue and yellow, shouldn't I get green? I see this sort of bluish gray color.

    ArtRage currently doesn't use a real-world correct colour blending system. It uses a sort-of additive gamma-corrected digital system in RGB space.
    In RGB space: Red + Blue = Magenta.
    Red + Yellow = Red + (Red + Green) = orange.
    Blue + Yellow = Blue + (Red + Green) = White (or grey)

    With real-world oil paints, most of the above combinations produce slight variations of 'mud'

    With subtractive inks in CMYK space, the results are different again.

    nice to know, Andy. I have been wondering about this myself too. Is there any plan to convert to a real-world correct colour blending method in a future release?

    It might happen. I'd like to experiment some.
