Color Theory & Formats Guide

HEX Colors

Hexadecimal color codes use base-16 numbering to represent colors. Each color is defined by 6 characters preceded by a hash (#).

  • Format: #RRGGBB (Red, Green, Blue)
  • Range: 00-FF for each channel (0-255 in decimal)
  • Example: #FF0000 = Pure Red
  • Short form: #RGB expands to #RRGGBB

RGB Colors

RGB (Red, Green, Blue) is an additive color model where colors are created by combining red, green, and blue light.

  • Format: rgb(r, g, b)
  • Range: 0-255 for each channel
  • Usage: Digital displays, web design
  • Alpha: rgba(r, g, b, a) includes transparency

HSL Colors

HSL (Hue, Saturation, Lightness) represents colors in a more intuitive way that matches human color perception.

  • Hue: 0-360° on the color wheel
  • Saturation: 0-100% color intensity
  • Lightness: 0-100% from black to white
  • Advantage: Easy to create color variations

HSV Colors

HSV (Hue, Saturation, Value/Brightness) is similar to HSL but uses brightness instead of lightness.

  • Hue: 0-360° color position
  • Saturation: 0-100% color purity
  • Value: 0-100% brightness level
  • Usage: Image editing, color selection

CMYK Colors

CMYK (Cyan, Magenta, Yellow, Black) is a subtractive color model used in printing.

  • Format: cmyk(c%, m%, y%, k%)
  • Range: 0-100% for each channel
  • Usage: Print media, professional printing
  • Black (K): Key color for text and details

Color Harmonies

Color harmonies are combinations of colors that are aesthetically pleasing and work well together.

  • Complementary: Opposite colors on the color wheel
  • Triadic: Three equally spaced colors
  • Analogous: Adjacent colors on the color wheel
  • Monochromatic: Variations of a single hue
  • Split-Complementary: Base color + two adjacent to complement

Accessibility & Contrast

Color accessibility ensures your designs are usable by people with visual impairments.

  • WCAG Guidelines: Minimum contrast ratios for text
  • Color Blindness: ~8% of men, ~0.5% of women affected
  • Best Practices: Don't rely solely on color for information
  • Testing: Use contrast checkers and simulators

CSS & Web Usage

Different color formats have specific use cases in web development and design.

  • HEX: Most common for CSS, compact notation
  • RGB: Precise control, good for calculations
  • HSL: Intuitive for creating color schemes
  • Transparency: Use rgba() or hsla() for opacity
