What is color theory?
Color theory is the set of principles governing the relationships between colors and how we perceive them. In web design, it guides the choice of color palettes to create interfaces that are attractive, readable and emotionally coherent. It is a pillar of UI/UX design with a direct influence on user experience and conversion rates.

Color harmonies
Harmonies are combinations built on the color wheel: complementary (opposite colors, strong contrast), analogous (neighbouring colors, gentle harmony), triadic (three equidistant colors, dynamic feel), split-complementary (a more subtle variation).
Color and web accessibility
WCAG standards require a minimum contrast ratio of 4.5:1 for standard text and 3:1 for large text. Tools such as a Contrast Ratio checker make it easy to verify compliance.
