Warm vs Cool Colors

The fundamental divide that shapes every emotional response to color.

Warm Colors

Advance toward the viewer • Energize • Stimulate action

Cool Colors

Recede from the viewer • Calm • Encourage reflection

The Science of Color Temperature

The warm/cool divide isn't just subjective — it's rooted in our evolutionary history. Warm colors (red, orange, yellow) are associated with sunlight, fire, and warmth. Cool colors (blue, green, purple) remind us of water, sky, and shade.

This isn't metaphor — warm colors literally appear to advance toward viewers, while cool colors recede. This optical phenomenon affects how we perceive space, importance, and emotion in design.

🧠 Psychological Fact

Studies show warm colors increase heart rate and stimulate appetite, while cool colors slow heart rate and suppress hunger. This is why fast food uses red/yellow and spas use blue/green.
