The first image is the baseline image with no color correction. Directly to its right is the daltonized image. In the lower left is a simulation of the original image as I see it before correction. In the final quadrant is a simulation of the corrected image, as I see it.

To put this in context, the two images on the left look identicale two me, as do the two images on the right.  8:16:34 PM     Add a comment
