maybe it is a white/green blotch, not sure, all the colors run together for me. No contrast to them. So, since you are all describing it so well, I blew it up and increased the contrast and now I can see what you are all talking about.
You know those pick the number out of the red and green dots type test things you did in school? I failed. Miserably. I cannot see the numbers. Colorblindness stinks.
