This is screen capture of the Vischeck Daltonize tool on one of my images. Upper left image is original; upper right is supposed to help non-color-blind people see how color-blind (red-green) folk see the original; lower left is the daltonized image to help color-blind folk see differences in color; lower right is supposed to help non-color-blind people see how color-blind folk see the daltonized version.

I circled the areas of the image that the daltonized version "brought-to-light" for me. These circled areas are not color-distinguished in the original as I view it with my color blind eyes.
