What is color theory in UI design?
Color theory is the foundation for creating harmonious and functional UI palettes.
It includes:
Primary, secondary, and tertiary colors
Color relationships like complementary, analogous, triadic
Temperature (cool vs. warm tones)
Psychological impact and visual hierarchy
In UI design, it helps you choose colors that work well together and support the product’s tone and usability.
