Color Theory Explained

Monochromatic: Variations in lightness and saturation of a single hue. This scheme looks clean and elegant, producing a soothing effect that is easy on the eyes.

Complementary: Colors that are opposite each other on the color wheel. This creates high contrast and high impact, ideal for highlighting key elements.

Analogous: Colors that are next to each other on the color wheel. They usually match well and create serene and comfortable designs found often in nature.

Triadic: Three colors evenly spaced around the color wheel. This scheme offers strong visual contrast while retaining balance and color richness.
