I'm having some difficulties with OmniGraffle exporting the wrong colors when I'm exporting a canvas as png.
My problem: If I create an empty canvas and set the canvas fill color to solid red (ff0000), export it as png, open the png in pixel editing software of my choice (Pixelmator) and the supposedly solid red shows up as ff1b18. Further investigation using DigitalColor Meter reveals that the "solid red" is actually ff1b18 in the OmniGraffle editing area as well! What's more disturbing is that even the preview color in the color picker window is ff1b18 although the sliders are at the 255,0,0 positions!
Perhaps this is not a OmniGraffle problem but rather some sort of generic system color profile problem. Still, I don't know what to do. Please help me! :)
Thanks!

Update: I just tried calibrating my display in System Preferences > Displays > Colors > Calibrate... and this did indeed change the exported colors, and the DigitalColor Meter reading inside of OmniGraffle as well. When trying my best to calibrate the display, "solid red" ends up as ff1a17 and when I on the other hand try to center all calibration sliders (as uncalibrated as possible?) I end up with ff1412. Still far away from actual solid red (ff0000).
Please advise!
