Understanding Color Basics

The Color Wheel

The color wheel is the foundation of color theory. It consists of 12 colors: 3 primary (red, yellow, blue), 3 secondary (orange, green, purple), and 6 tertiary colors. Understanding the relationships between these colors is key to creating harmonious designs.

Color Properties

Hue
The pure color itself - red, blue, green, etc. This is what we typically mean when we say "color."
Saturation
The intensity or purity of a color. Highly saturated colors are vivid, while desaturated colors appear more muted or gray.
Lightness (Value)
How light or dark a color is. Adding white creates tints, while adding black creates shades.

Color Harmony Rules

Color harmony creates pleasing, balanced color combinations. Here are the most common harmony rules:

Complementary

Colors opposite on the color wheel (e.g., blue & orange). Creates high contrast and vibrant designs.

Analogous

Colors adjacent on the wheel (e.g., blue, blue-green, green). Creates harmonious, serene designs.

Triadic

Three colors evenly spaced on the wheel. Offers vibrant contrast while remaining balanced.

Monochromatic

Variations of a single hue. Creates cohesive, sophisticated designs with different tints and shades.

Color Psychology in Web Design

Colors evoke emotions and influence user behavior. Understanding color psychology helps create designs that resonate with your audience:

Red
Energy, passion, urgency. Often used for call-to-action buttons and sales. Can increase heart rate and create excitement.
Blue
Trust, professionalism, calm. Popular for corporate sites, social media, and finance. The most universally liked color.
Green
Growth, health, nature. Perfect for environmental, health, and financial brands. Associated with prosperity and balance.
Yellow
Optimism, warmth, attention. Grabs attention but use sparingly. Can cause eye strain in large amounts.
Purple
Luxury, creativity, wisdom. Often used for beauty, premium products. Combines the energy of red with blue's calm.
Orange
Confidence, enthusiasm, friendly. Great for calls-to-action. Less intense than red but still energetic.

Color Accessibility

Accessible color choices ensure your website is usable by everyone, including people with color blindness or visual impairments.

WCAG Contrast Guidelines

Beyond Contrast

  • Never rely on color alone to convey information
  • Use patterns, icons, or text labels in addition to color
  • Test with color blindness simulators
  • Provide sufficient visual cues for interactive elements

Best Practices for Web Design

Building a Color Palette

  1. Choose a primary color that represents your brand or purpose
  2. Select 1-2 secondary colors for accents and variety
  3. Add neutral colors (grays, whites, blacks) for text and backgrounds
  4. Create variations of each color for different uses (hover states, etc.)
  5. Test accessibility for all text and background combinations

Common Mistakes to Avoid

  • Using too many colors (stick to 3-5 main colors)
  • Poor contrast between text and background
  • Ignoring color psychology for your audience
  • Not considering color blindness
  • Copying competitor colors without strategic reason
