About the RGB to HEX Color Converter

The RGB to HEX Color Converter instantly converts RGB color values to their hexadecimal equivalents and back. Enter any RGB value (like rgb(255, 128, 0)) and get the corresponding hex code (#FF8000) — or enter a hex code to see the RGB breakdown. Essential for web developers and designers moving between design tools and CSS code.

How to use it

  1. Enter RGB values (0-255 for red, green, and blue channels).
  2. Or paste a hex code to convert it to RGB.
  3. See the color preview update in real time.
  4. Copy the converted value in your preferred format.

Formula & methodology

RGB to HEX: each channel (0-255) converted to 2-digit hexadecimal. Red: dec_to_hex(R), Green: dec_to_hex(G), Blue: dec_to_hex(B). Concatenate with # prefix: #RRGGBB. Example: rgb(255, 128, 0) = #FF8000. HEX to RGB: R = hex_to_dec(first 2 chars), G = hex_to_dec(middle 2), B = hex_to_dec(last 2). Shorthand #RGB: expand each digit (e.g., #F80 = #FF8800).

Common use cases

  • Converting design tool colors (Figma, Sketch) to CSS hex codes
  • Translating brand color specifications between formats
  • Web development: CSS color values in both rgb() and hex formats
  • Comparing colors by understanding their RGB channel breakdown
  • Converting printer CMYK designs (via intermediate RGB) to web hex

Frequently asked questions

Both are fully equivalent for opaque colors. Hex (#FF8000) is shorter and more common in traditional CSS. rgb() and hsl() are more readable (you can tell if a color is greenish by looking at the G channel). Use rgba() or hsla() when you need transparency (alpha channel). Modern CSS also supports color-mix(), oklch(), and other color functions. For consistency in a codebase, pick one convention and stick to it.
#000000 is pure black (all RGB channels at 0). #FFFFFF is pure white (all RGB channels at maximum 255). #FF0000 is pure red, #00FF00 is pure green, #0000FF is pure blue. #808080 is medium gray (128, 128, 128). The hex system encodes the full 16 million color gamut of 8-bit RGB (256^3 = 16,777,216 possible colors).
