I seem to be having a color management problem. I don't know how to fix it. When I export my drawing from Inkscape as PNG and open it in Windows photo viewer or Adobe Lightroom, the colors don't match those I see in Inkscape. However, if I view the image in Windows 8 Photo app (Metro app), the colors do seem to match Inkscape. I have created a color profile for my monitor. I have tried to change Inkscape's settings to use it through Document Properties > Color > Linked Color Profiles as well as Preferences > Input/Output > Color Management. Changing those settings don't seem to have any effect on the colors when I export the drawing. I'm a newbie when it comes to color management, so I don't know what I should be doing to preserve the colors.
