Beginner Tip #2 – Color Dependency

Difficulty: Beginner


  • Presentation

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.
