Math Color Debate Origins

The Internet loves getting into low-stakes debates, like wondering if cereal is a soup or how to pronounce GIF. The latest question that has people reconsidering their whole lives: what color is math? Students, teachers, and adults looking back on their school days are fiercely debating why math is red or blue (and which color folder to use for the subject). Below, we break down both sides of the debate, the colors of other subjects, and why we associate colors with school subjects to begin with.

What color is math?

While there’s no right answer, many people associate math with red or blue. Red is a fiery color that evokes strong emotions, just like the subject of math does. However, some people find math calming and logical, so they associate it with blue. Which color you think math is likely depends on childhood associations.

$Math may be blue because blue is associated with serenity and orderliness.$
Math may be blue because blue is associated with serenity and orderliness. Not everyone struggles with math—and those who enjoy the subject might find a sense of calm in the neat consistency of solving problems. If you find math relaxing and serene, you may associate it with blue because the color evokes the same feelings as the subject for you.^{[5]

- It’s also possible that your teacher color-coded the subject as blue by using blue worksheets and books. Or, you chose to use blue notebooks and folders for the subject, developing a subconscious association between the color and the subject.
- Beyond color associations, math fans may even see the math formulas in a positive light. One study found that mathematicians’ emotional brain centers—the same area of the brain activated when appreciating beauty in art—were activated by math equations they rated as beautiful.^{[6]

Seeing words as colors could be a sign of grapheme-color synesthesia. While not a medical condition, synesthesia describes a phenomenon in which people feel like two unrelated senses are connected—for example, tasting numbers by experiencing a flavor when you see or think of them. Grapheme-color synesthesia is a type of synesthesia in which graphemes (letters, numbers, or symbols) are seen as colors. This phenomenon could explain why some people feel strongly about what color math is.^{[9]
