How to: Setting Custom Colors via Environment Variable
You can specify custom colors via the `JC_COLORS` environment variable. The
`JC_COLORS` environment variable takes four comma separated string values in
the following format:
```bash
JC_COLORS=
,

,
```

Where colors are: `black`, `red`, `green`, `yellow`, `blue`, `magenta`, `cyan`,
`gray`, `brightblack`, `brightred`, `brightgreen`, `brightyellow`, `brightblue`,
`brightmagenta`, `brightcyan`, `white`, or  `default`

For example, to set to the default colors:
```bash
JC_COLORS=blue,brightblack,magenta,green
```
or
```bash
JC_COLORS=default,default,default,default
```
