Command-line tool for looking up colors

Project description


Command-line tool for quickly looking up colors, shades and palettes.

Supported color models: HEX, RGB, HSL, HSV, CMYK

Build CodeQL Codecov


  • Modern terminal with true color and utf-8 support (e.g. Windows Terminal, PowerShell, iTerm2, Terminator)
  • Python 3.6+


Install via pip:

pip install colorpedia

Add the following line in .bashrc for autocompletion (only bash supported):

source <(color -- --completion)

Restart your shell to use the color command:

color --help

If you have a name collision on Windows, you can use colorpedia instead:

colorpedia --help


Look up colors using various color models:

color name green            # CSS3 color name
color hex FFFFFF            # hex code without the hash (#) prefix
color rgb 255 255 255       # RGB (Red Green Blue)
color hsl 360 100 100       # HSL (Hue Saturation Lightness)
color hsv 360 100 100       # HSV (Hue Saturation Brightness)
color cmyk 100 100 100 100  # CMYK (Cyan Magenta Yellow Black)

Use --shades to display shades of a color (dark to light):

color name green --shades    # Display 15 colors by default
color hex FFFFFF --shades=5  # Display 5 shades

Look up color palettes:

color palette molokai
color palette zenburn
color palette blue
color palette kelly

Control the output with global flags:

color name yellow --all      # Display all details
color name yellow --json     # Display in JSON format
color name yellow --units    # Display unit symbols
color name yellow --nojson   # Do not display in JSON
color name yellow --nounits  # Do not display unit symbols

Combine with other tools like jq:

color palette molokai | cut -d'|' -f 2,3,4
color name blue --range --json | jq .[0].name


Initialize the config file to customize CLI behavior:

color config init

The command above creates ~/.config/colorpedia/config.json with default settings:

  // Always display in JSON format. Use with --nojson flag.
  "always_output_json": false,
  // Suffix for approximate color names (e.g. "green (approx)").
  "approx_name_suffix": " (approx)",
  // Default number of shades displayed when --shades is used without a count.
  "default_shades_count": 15,
  // Display degrees angle (°) symbol. Use with --nounits flag.
  "display_degree_symbol": false,
  // Display percentage (%) symbol. Use with --nounits flag.
  "display_percent_symbol": false,
  // Height of the color box displayed in single-color (get) view.
  "get_view_color_height": 10,
  // Width of the color box displayed in single-color (get) view.
  "get_view_color_width": 20,
  // Keys displayed in single-color (get) view.
  "get_view_keys": [
  // Keys displayed in JSON view.
  "json_keys": [
  // Width of the color box displayed in multi-color (list) view.
  "list_view_color_width": 20,
  // Keys displayed in multi-color (list) view.
  "list_view_keys": [
  // Always uppercase hex codes if set to true, lowercase if set to false.
  "uppercase_hex_codes": true

Handy shortcuts to view and edit the configuration file:

color config show  # Display configuration
color config edit  # Edit configuration via a text editor

Use --help to see more information on each subcommand:

color config --help
color rgb --help
color palette --help

Technical Notes

  • Names of "unknown" colors are approximated using minimum RGB delta:
    delta = (R1 - R2) ^ 2 + (G1 - G2) ^ 2 + (B1 - B2) ^ 2
    If there is are ties, all names are included in the output using / delimiter.
  • Percentage values use 0 - 100 scale by default, 0 - 1 scale in JSON.
  • Degree angles use 0 - 360 scale by default, 0 - 1 scale in JSON.
  • Percent and degree unit symbols are omitted in JSON.
  • If HSV/HSL/CMYK values do not map exactly to an RGB triplet, they are rounded to the nearest one.
