A cow-orker in the next cube is red/green colorblind and most often cannot tell between the two (even with solid colors).

There's also blue/yellow colorblind (more rare). :-) -- Chris Adams <cmadams@xxxxxxxxxx> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble. -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
