From the same Author that brought us command line essentials like `fd` and
`bat` written in rust comes [pastel](https://github.com/sharkdp/pastel) an
incredible command-line tool to generate, analyze, convert and manipulate
colors.

## Install

You can install from one of the
[releases](https://github.com/sharkdp/pastel/releases), follow the
[instructions](https://github.com/sharkdp/pastel#installation) for your system
from the repo. I chose to go the nix route. I have enjoyed the simplicity of
the nix package manager being cross platform and have very up to date packages
in it.

```bash
nix-env --install pastel
```

## Mixing colors

Something I often do to blend colors together is add a little alpha to
something over top of a background. I can simulate this by mixing colors.

```bash
pastel color cornflowerblue | pastel mix goldenrod -f .1
```

Here is one from the docs that show how you can generate a color palette from
random colors, mix in some red, lighten and format all in one pipe.

```bash
pastel random | pastel mix red | pastel lighten 0.2 | pastel format hex
```

## color picker

I am on Ubuntu 20.10 as I write this and it works flawlessly. When I call the
command, a color picker gui pops up along with an rgb panel. I can pick from
the panel or from anywhere on my screen.

```bash
pastel color-picker
```

 Sorry, your browser doesn't support embedded videos.

## Conversions

I often will want to convert a color from rgb to hex or hsl vice versa. I open
google and search. This is one part that I could really use adding to my
workflow.

## Check it

Here I can mix up a dark grey with rgb, mix in 20% cornflowerblue, and grab the
hex value.

```bash
pastel color 50,50,50 | pastel mix cornflowerblue -f .2
```

I really want to get this into my workflow. I saw it quite awhile ago but have
not done much color work. Lately I have been doing a bit more front end, and
have been getting into game development. This is the time to stop googling
random color mixers and use this one.
