During the recent debate on the new icon theme I brought the question of testing your work against known vision defects like red/green color blindness, blurry vision and such things. However it does not seem that we have an easy to use tool to simulate all these various issues, therefore I would like to propose that we work on building one. I would be willing to dust off my coding skills and give this a shot however I need some help figuring out the math behind the various defects.
I started a new thread on this; you might want to check out some of the links I cited as they have equations that may be useful for blurred vision impairments.
I have been able to dig up all kinds of genetic details as to how this works but not a single reference to an algorithm we could apply to the transform operation.
From googling for 'color blindness simulation equations' I unearthed the following references:
[1] http://steve.hollasch.net/cgindex/color/color-blind.html "Color Blindness Theory, Simulation"
[2] http://vision.psychol.cam.ac.uk/jdmollon/papers/Dichromat_simulation.pdf "Computerized simulation of color appearance
for dichromats" I'm sure further googling will produce more reference materials. ~m _______________________________________________ @xxxxxxxxxx http://www.redhat.com/mailman/listinfo/
