TL;DR
- Complementary colors (opposite on the color wheel) create contrast; analogous colors (next to each other) create harmony.
- Use the 60-30-10 rule: 60% dominant color, 30% secondary, 10% accent.
- Check contrast ratio for text on colored backgrounds — readability beats aesthetic preference every time.
You don’t need art school to pick colors that work together — a handful of relationships explain most of what “looks right” or “looks off” in a color palette.
The color wheel relationships that actually matter
Complementary colors sit opposite each other on the color wheel (like blue and orange). They create high contrast and energy — useful for a single accent color you want to stand out, but overwhelming if used for large areas.
Analogous colors sit next to each other (like blue, teal, and green). They create a harmonious, low-tension palette — a safe default for backgrounds and larger areas where you don’t want visual competition.
Triadic colors are evenly spaced around the wheel (like red, yellow, blue). They’re vibrant and balanced but harder to use well — usually best with one color dominant and the other two as small accents.
The 60-30-10 rule
A simple, reliable starting ratio: 60% of a design in your dominant color, 30% in a secondary color, and 10% in an accent color for buttons and highlights. It’s not a hard law, but it prevents the most common beginner mistake — too many colors competing for equal attention.
Readability comes before aesthetics
A palette that looks great as swatches can still fail in practice if text contrast is too low. Check that body text has enough contrast against its background (WCAG recommends a 4.5:1 ratio for normal text) before finalizing any palette.
FAQ
What’s the easiest color scheme for beginners?
Analogous color schemes (colors next to each other on the wheel) are the safest and easiest to get right, since they naturally harmonize.
What is the 60-30-10 rule in design?
A ratio guideline: 60% dominant color, 30% secondary color, 10% accent color, used to prevent too many competing colors in a design.
How do I check if my text color has enough contrast?
Use a contrast checker tool to verify your text-to-background contrast ratio meets at least 4.5:1 for normal text, per WCAG accessibility guidelines.
