    Hi Heikki
    ArtRage applies lighting across the canvas. The top left is generally slightly lighter than the bottom right of the canvas surface. It makes it look a bit more real that a simple flat colour.
    No colours in ArtRage will exactly match the colours you choose. When we were designing ArtRage and working out the lighting model, we wanted something that 'felt good' rather than was exactly numerically accurate.

    This does mean ArtRage is not suitable for many uses that require exact colour-matching.
    Even the default paper isn't exactly white - it has a slight yellowish tinge. This more closely matches the feel of a canvas lit with warm lights.
    Additionally, most of the canvas textures in ArtRage have a slightly roughened surface, and when the light is applied it can vary the colour very slightly in small local areas to give the texture of the paper.

    Hi, and thanks clear answer. I get the point of yours. Now i understand more better how program works and i can handle this color-system.

    Normal art-drawing paint it is not a problem.

    Mainly it is problem only when i use net-gallery drawings without frames or using magazine press without frames or somekind box round of picture.

    Like you see my artkuvia page, there is that same goosedrawing with frame and then color-difference between drawing-netpage is not problem.
    ( I remove my temp page where was this goose-drawing without frames.)

    (I think that opacity selection is usefull of this too with using .png format also.)

    So color-thing is clear for my and i handle it. Ok.

    Thanks again and Hi.
