Expand description

ColorChoice represents the color preferences of an end user.

## Variants

### `Always`

Try very hard to emit colors. This includes emitting ANSI colors on Windows if the console API is unavailable.

### `AlwaysAnsi`

AlwaysAnsi is like Always, except it never tries to use anything other than emitting ANSI color codes.

### `Auto`

Try to use colors, but don’t force the issue. If the console isn’t available on Windows, or if TERM=dumb, or if `NO_COLOR` is defined, for example, then don’t use colors.

### `Never`

Never emit colors.
