Calico �?�

Calico is a small utility written in Haskell which is cat but for colors.

It accepts input in the form of an Aseprite palette, a GPL palette, or delimited hex colors.

Its output is highly configurable, and it is able to convert between RGB and HSL.

It also features a primitive command language for modifying the hue, saturation and luminosity values of all colors in the palette.

Demonstration

Bash, Fish and Zsh completion

Thanks to optparse-applicative, calico can automatically generate completion scripts for various shells. Instructions can be found here and require minimal effort on the user's part.

Motivations

calico was born out of a frustration with having to open a full image editor in order to view the colors contained within a palette. It makes use of true-color terminal escape codes to display the colors with accuracy on the command line.
