Color is an excellent and essential design tool to draw the eye toward certain information
and signal importance. However, for those with visual impairments or color blindness,
the important information might go unnoticed or without emphasis. There are two main
concerns when using color.

Use color. Color is an effective tool for emphasis and design. Just keep in mind that
color should not work alone in conveying important information to your audience.
When color is used, be sure to use sufficiently contrasting colors to help your information
be easily seen. Use an online color contrast checker to make sure your colors are
working. The legal standard to meet is the WCAG 2.0 AA standard.
