Color contrast is defined as how one color stands out from another color and is important for certain populations such as low vision viewers or those with color blindness. The goal of color contrast is so users can read text that is presented over a background. Key points for consideration of color and color contrast include:

  • Use an accessibility tool to ensure that contrast between text and background color is at least 4.5:1.
  • Color contrast should be evaluated in charts and graphs for colors that are next to each other so that they meet the 4.5:1 contrast ratio.
  • When using color, do not use color as the only way to convey the meaning.
