How does RexLex Work with Color Blindness?

The term color blindness almost never indicates a full lack of color. Virtually all people who are “color blind” are missing the ability to detect either red or green, thus collapsing them into one. The effect is similar to dividing things into warm lights and cool lights vs a full spectrum. Below this is simulated in the column labeled “2 Color”. RexLex has been carefully engineered to simultaneously maximize letter distinction for both 2 color and normal 3 color readers. The letters are most distinct using all 3 colors, but the separation with 2 colors is still vastly more than with B&W.

Rexlex is providing the brain with 5 additional dimensions of measurements. The colorblind are still being provided with 4 of 5: either red or green, blue, variable brightness, an entire array of peripheral sensors.
