Did you know there’s a psychology behind colors? That’s because colors affect our emotions and physical state. Red can quicken the pulse, blue can calm someone down, and yellow can cause eye strain and irritation. This information is important to know when you’re developing e-learning and choosing color schemes.

However, I do want to note that the definitions in this article are targeted mostly for western cultures. Depending on the culture or country specific to your learners, colors might have different meanings and significance, so know your audience.
