Comment 2 for bug 170565

Actually, the linked page has a pretty nice description of the issue. I'm not sure if the new color management code takes care of this or not...

As I understand it, the problem is that doing linear interpolation across color boundaries when doing antialiasing, even though mathematically correct, can introduce color and luminance fringes, since linear interpolation doesn't produce *perceptually* smooth gradients...

The next step in this bug would be fore someone motivated to test the new LCMS feeatures in Inkscape 0.46 to see if this is currently handled correctly. If not, some test SVG files and test PNG renders would certainly help generate developer interest...
