Photoshop CS4 accessibility overview. Colorblind Web Page Filter. Color blindness. Color blindness, or color vision deficiency, is the inability or decreased ability to see color, or perceive color differences, under normal lighting conditions.
Color blindness affects a significant percentage of the population.[1] There is no actual blindness but there is a deficiency of color vision. The most usual cause is a fault in the development of one or more sets of retinal cones that perceive color in light and transmit that information to the optic nerve. This type of color blindness is usually a sex-linked condition. The genes that produce photopigments are carried on the X chromosome; if some of these genes are missing or damaged, color blindness will be expressed in males with a higher probability than in females because males only have one X chromosome (in females, a functional gene on only one of the two X chromosomes is sufficient to yield the needed photopigments).[2] Background[edit] Classification[edit] By cause[edit] By clinical appearance[edit] Causes[edit] Types[edit]
