Reverse Color Blindness Test "normal vision humans have a lower degree of color contrast detection in the red spectrum. A colorblind person shouldn't be burdened by that lowered contrast sensitivity and should be able to see the object immediately by picking out the change in contrast at the objects edges" A small oddity that takes but a few seconds of time.
