What is Color Theory?


Color theory is a set of principles and guidelines for using color effectively in design, art, and visual communication. It encompasses the relationships between colors, their psychological effects, and how they can be combined to create harmonious and impactful designs.


Understanding Color Theory


Color theory is based on the color wheel and provides a framework for understanding how colors interact with each other and how they affect human perception and emotion.


The Color Wheel


The color wheel is a circular arrangement of colors that shows the relationships between primary, secondary, and tertiary colors.


#### Primary Colors

  • Red: Energy, passion, excitement
  • Blue: Trust, stability, calm
  • Yellow: Optimism, creativity, warmth

    • #### Secondary Colors

  • Green: Growth, harmony, nature (Blue + Yellow)
  • Purple: Luxury, creativity, mystery (Red + Blue)
  • Orange: Energy, enthusiasm, adventure (Red + Yellow)

    • #### Tertiary Colors

  • Red-Orange: Confidence, courage
  • Yellow-Orange: Joy, optimism
  • Yellow-Green: Freshness, growth
  • Blue-Green: Tranquility, healing
  • Blue-Purple: Wisdom, dignity
  • Red-Purple: Royalty, luxury

    • Color Harmonies


    Complementary Colors

  • Colors opposite each other on the color wheel
  • Create high contrast and visual impact
  • Examples: Red and Green, Blue and Orange, Yellow and Purple

    • Analogous Colors

  • Colors next to each other on the color wheel
  • Create harmony and serenity
  • Examples: Blue, Blue-Green, Green

    • Triadic Colors

  • Three colors equally spaced on the color wheel
  • Create vibrant and balanced designs
  • Examples: Red, Yellow, Blue

    • Split-Complementary

  • One base color and two colors adjacent to its complement
  • High contrast with less tension than complementary
  • Examples: Blue, Red-Orange, Yellow-Orange

    • Tetradic (Double Complementary)

  • Two pairs of complementary colors
  • Rich and complex color schemes
  • Examples: Red, Green, Blue, Orange
