1. The Color Wheel

The color wheel is a circular diagram that organizes colors based on their relationships. It helps artists, designers, and planners understand how colors interact.

Structure of the Wheel

  1. Primary Colors (cannot be created by mixing other colors):
    • Red, Blue, Yellow.
  2. Secondary Colors (created by mixing two primaries):
    • Orange (Red + Yellow)
    • Green (Yellow + Blue)
    • Violet/Purple (Blue + Red)
  3. Tertiary Colors (mix of one primary and one secondary):
    • Red-Orange, Yellow-Orange, Yellow-Green, Blue-Green, Blue-Violet, Red-Violet.

👉 The wheel helps us visualize harmony, contrast, and balance in color use.


2. Key Definitions in Color Theory

  • Hue: The pure color (e.g., red, green, blue).
  • Tint: A hue + white (lighter version).
  • Shade: A hue + black (darker version).
  • Tone: A hue + gray (muted version).
  • Saturation (Intensity): The brightness or dullness of a color.
  • Value: The lightness or darkness of a color.
  • Warm Colors: Reds, oranges, yellows → energetic, attention-grabbing.
  • Cool Colors: Blues, greens, purples → calming, receding.

3. Color Schemes

Color schemes are planned combinations of colors that create harmony, contrast, or emphasis.

(a) Monochromatic Scheme

  • Uses variations of one hue (with tints, shades, and tones).
  • Example: Light blue, medium blue, navy.
  • Effect: Elegant, unified, calm.

(b) Analogous Scheme

  • Uses colors next to each other on the wheel.
  • Example: Blue, blue-green, green.
  • Effect: Harmonious, natural (like landscapes).

(c) Complementary Scheme

  • Uses colors opposite each other on the wheel.
  • Example: Red & Green, Blue & Orange.
  • Effect: High contrast, vibrant.

(d) Split-Complementary Scheme

  • One base color + the two adjacent to its complement.
  • Example: Blue with Yellow-Orange and Red-Orange.
  • Effect: Contrast with less tension than direct complementary.

(e) Triadic Scheme

  • Three colors evenly spaced on the wheel.
  • Example: Red, Yellow, Blue.
  • Effect: Balanced, dynamic.

(f) Tetradic (Double Complementary) Scheme

  • Two pairs of complementary colors.
  • Example: Blue & Orange with Green & Red.
  • Effect: Rich, diverse, but needs careful balance.

(g) Neutral Scheme

  • Uses blacks, whites, grays, and sometimes browns/beiges.
  • Effect: Minimalist, timeless, often used as a background for accent colors.

4. Applications of Color Theory

  • Design & Architecture: Establish mood, function, and identity of spaces.
  • Cartography & Planning: Differentiate land uses or highlight key zones.
  • Graphics & Branding: Create recognition and emotional impact.
  • Fine Arts: Convey atmosphere, emotion, and symbolism.

Quick Practice Exercise:

  • Draw a 12-color wheel (Primary, Secondary, Tertiary).
  • Create small swatches showing:
    1. Monochromatic
    2. Analogous
    3. Complementary
    4. Triadic
  • Reflect on how the combinations feel different in mood and function.
