How can we create color save content for people who are color blind?
For example? What’s the difference between these two lists?
One is green and the other is red.
What about these two lists?
Both of these look yellow.
Keep in mind that even if colors seem to be different, as with the first pair, they might appear the same as with the second pair, depending on a person’s colorblindness.
Never convey meaning using only colors.
Always convey meaning using multiple modes, in this case, both with color and text.
In that way, meaning is conveyed regardless of a person’s color sensitivity.
Use a colorblindness checker to ensure accessible colors.

The first step in creating more universally accessible instructional materials is awareness. This informational video on color blindness helps people understand people’s perspectives on color blindness and the importance of color choices in creating instructional materials.
How to Use This Video
Here are some suggestions on using this video:
- Instructors might include this video as a part of a course and ask students to review webpage color sc schemes and how that may affect someone who is colorblind.
- Individuals might use this video to raise awareness in their department for a disability awareness event.
- Presenters might use this video as a part of their accessibility training.
- Red-green color vision defects are the most common form of color vision deficiency. It occurs in about 1 in 12 males and 1 in 200 females among populations with Northern European ancestry.
- Blue-yellow color vision defects affect males and females equally. This condition occurs in fewer than 1 in 10,000 people worldwide.
- Blue cone monochromacy is rarer than the other forms of color vision deficiency, affecting about 1 in 100,000 people worldwide. Like red-green color vision defects, blue cone monochromacy affects males much more often than females.
Make sure that colors are not the only method of conveying important information.
