[Washington Assistive Technology Act Program]

This is part of a continuing series of web accessibility tips for IT
personnel, web managers and web development groups. These tips can be
used to review current website accessibility and to utilize in
developing new websites with the hope of improving web accessibility
for everyone.

Individuals with color-blindness or color deficiency may have
difficulty in differentiating between certain color combinations. This
affects approximately 7% of males and .1% of females. Difficulty in
differentiating red and green is most common - these are most often the
colors used to convey meaning or differences. While using appropriate
colors, providing good color contrast, and not using color as the only
means of conveying content is important for those with color-blindness
or color deficiency, these techniques may also improve accessibility to
those who are blind (screen readers do not typically identify color) or
have low vision (these users may override page colors to make the page
more readable). An easy test for color dependency is to print the page
on a black and white printer and see if any information is missing when
the color is removed from the page.
