How to Convert Between Color Formats

Formula

Hex components equal the decimal RGB values in base-16.
Lightness = (max(R,G,B) + min(R,G,B)) / 510 × 100.

Color conversion between RGB, hex, HSL, and CMYK is essential for web design, print design, and digital art. This converter takes RGB input values and provides equivalent representations.

RGB uses values from 0-255 for red, green, and blue channels. Hex is simply these values in base-16. HSL represents color as hue, saturation, and lightness.

Common use cases:

  • Web development CSS color specifications
  • Graphic design color matching
  • Converting screen colors for print production
