Color Code Converter

Convert colors between HEX, RGB, HSL, CMYK, and decimal formats. Useful for decoding color-based puzzles.

e.g., #FF5733 or FF5733

Common Color Values

Puzzle Applications

  • • RGB values can encode coordinates (R=lat degrees, G=minutes, B=seconds)
  • • HEX codes contain hidden numbers (4A = 74, 7C = 124)
  • • Decimal color values may be direct coordinate components
  • • Color sequences can spell words using first letters

Color Code Formats

Colors can be represented in many different formats, each useful for different applications and puzzles.

HEX Colors

Hexadecimal color codes use 6 digits (e.g., #FF5733) representing red, green, and blue values from 00-FF (0-255). This is the most common web format.

RGB

RGB (Red, Green, Blue) uses three decimal numbers from 0-255. This format directly represents how screens display colors by mixing light.

HSL

HSL (Hue, Saturation, Lightness) is more intuitive for humans:

  • Hue: Color angle (0-360°) on the color wheel
  • Saturation: Color intensity (0-100%)
  • Lightness: Brightness (0-100%)

CMYK

CMYK (Cyan, Magenta, Yellow, Key/Black) is used for printing. It's a subtractive color model, unlike the additive RGB.

Colors in Geocaching

Color codes appear in puzzles in various ways:

  • Direct encoding: RGB values as coordinate parts
  • Hex extraction: Numbers hidden in hex codes
  • Color names: First letters spelling messages
  • Resistor colors: Using color-to-digit mapping
