I want to color correct my digital photos, but I have a color vision deficiency. Up to now, I've been correcting the levels manually, but relying on the auto-color features in Picasa or Photoshop for colors, but often this doesn't do a good job and the colors look off, even to me. I can manually correct the levels and adjust the colors so they look right to me, but that doesn't guarantee they will look right to others. Is there any way to color correct numerically (for instance, using the eyedropper tool on someone's face to to see if the RGB value of skin falls within a skin-tone range) Otherwise, is there a service that I can send my digital photos to where they can color correct them perfectly and send them back? I'm interested in the digital files, not in getting prints.
Are those contact lenses that compensate for red/green colour blindness actually any use? [more inside]
Is there a perceptual (non-physical) component to colorblindness that can be cured or mitigated by training? [more inside]
Am I color blind? Because "The Green" looks more brown to me than anything else. [more inside]
