As designers, we have special interest in color blindness — more correctly called “Color Vision Deficiency” and more properly called Dyschromatopsia — as we work daily with colors.

We can better provide for those with color vision deficiencies by taking it into consideration as we design our websites, ads, illustrations, logos, typography or any visual communications. Protanomaly Protanopia
