Color Theory Tip
Complementary Colors
Colors directly opposite on the color wheel create maximum contrast and visual impact. This pairing naturally draws attention.
Usage tip: Use the complement sparingly as a CTA or accent color. Too much of both can create visual tension — let one dominate.

Color Roles
Assign each color a job, then pick a neutral base for the preview.
Dominant brand color — hero band & key sections
Supporting color — bands, chips & icons
The pop — buttons, links & highlights
Backgrounds & large calm areas (whites / grays)
Great designs lean on the neutral base for most of the page, letting your primary and secondary colors do the heavy lifting and the accent create a small, deliberate pop.
