Frequently Asked Questions

Complementary colors are opposite each other on the color wheel, creating strong contrast. Analogous colors are adjacent on the wheel, producing a natural, harmonious feel. Complementary is ideal for high-impact designs, while analogous works best for cohesive, unified aesthetics.
Triadic harmony uses three colors equally spaced (120° apart) on the color wheel. It creates rich, balanced color schemes. Use one as the dominant color and the other two as accents for the most effective results.
Monochromatic schemes use a single hue with variations in saturation and lightness. They're ideal for elegant, cohesive designs — commonly used in branding, minimalist design, and gradient backgrounds.
WCAG recommends a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text (18px+ or 14px bold). AAA level requires 7:1 for normal and 4.5:1 for large text.

Complete Guide to Color Palettes and Color Theory

Understanding color theory is essential for effective design. The right color palette strengthens brand identity and enhances user experience.

Fundamentals of Color Theory

Color theory is based on the color wheel and explains relationships between colors. Through combinations of primary (red, yellow, blue), secondary (orange, green, purple), and tertiary colors, infinite color schemes can be created. Complementary colors provide striking contrast, while analogous colors offer natural harmony.

Using Color Palettes in Web Design

Web design palettes typically consist of primary, secondary, accent, and neutral colors. Applying the 60-30-10 rule (60% primary, 30% secondary, 10% accent) creates visually balanced designs. Maintaining sufficient contrast between text and background is crucial for accessibility.
