Frequently asked questions
What is a complementary color?
The color directly opposite on the color wheel (180° away in hue). High contrast — ideal for CTAs and highlights against a dominant color.
What is an analogous palette?
Colors adjacent on the color wheel (±30° and ±60°). Creates harmonious, low-contrast combinations common in nature-inspired designs.
What is a triadic palette?
Three colors evenly spaced 120° apart on the wheel. Vibrant and balanced — often used in logo design.
What is split-complementary?
The two colors flanking the complement (150° and 210° away). High contrast like complementary, but less tension — easier to use.
