It supports many different color formats and color spaces like RGB (sRGB), HSL, CIELAB, CIELCh as well as ANSI 8-bit and 24-bit representations. 10 11## In action 12 13 14 15## Tutorial 16 17### Getting help 18 19`pastel` provides a number of commands like `saturate`, `mix` or `paint`. To see a complete list, you can simply run 20``` bash 21pastel 22``` 23To get more information about a specific subcommand (say `mix`), you can call `pastel mix -h` or `pastel help mix`. 24 25### Composition 26 27Many `pastel` commands can be composed by piping the output of one command to another, for example: 28``` bash 29pastel random | pastel mix red | pastel lighten 0.2 | pastel format hex 30``` 31 32### Specifying colors 33 34Colors can be specified in many different formats: 35``` 36lightslategray 37'#778899' 38778899 39789 40'rgb(119, 136, 153)' 41'119,136,153' 42'hsl(210, 14.3%, 53.3%)' 43``` 44 45Colors can be passed as positional arguments, for example: 46``` 47pastel lighten 0.2 orchid orange lawngreen 48``` 49They can also be read from standard input. So this is equivalent: 50``` 51printf "%s\n" orchid orange lawngreen | pastel lighten 0.2 52``` 53You can also explicitly specify which colors you want to read from the input. For example, this mixes `red` (which is read from STDIN) with `blue` (which is passed on the command line): 54``` 55pastel color red | pastel mix - blue 56``` 57 58### Use cases and demo 59 60#### Converting colors from one format to another 61 62``` bash 63pastel format hsl ff8000 64``` 65 66#### Show and analyze colors on the terminal 67 68``` bash 69pastel color "rgb(255,50,127)" 70 71pastel color 556270 4ecdc4 c7f484 ff6b6b c44d58 72``` 73 74#### Pick a color from somewhere on the screen 75 76``` bash 77pastel pick 78``` 79 80#### Generate a set of N visually distinct colors 81 82``` 83pastel distinct 8 84``` 85 86#### Get a list of all X11 / CSS color names 87 88``` bash 89pastel list 90``` 91 92#### Name a given color 93 94``` bash 95pastel format name 44cc11 96``` 97 98#### Print colorized text from a shell script 99 100``` bash 101bg="hotpink" 102fg="$(pastel textcolor "$bg")" 103 104pastel paint "$fg" --on "$bg" "well readable text" 105``` 106 107``` bash 108pastel paint -n black --on red --bold " ERROR!
