Because a significant number of users are colorblind, it's important that color shouldn't be the only way to indicate meaning.
It's common to use red and green to indicate a good or bad status; it's easy for many people to get a quick feel of a dashboard, for example, by using those colors. To make it accessible, we just need to add additional patterns or icons to clarify the status for color-blind users.
Instead of red and green circles, there are additional visual cues in this example:
- The red is shaped like a stop sign, and has an X in the center
- The green has a check mark
Remember, it's OK to use color to indicate meaning as long as the color isn't the only indicator.
