# Keywords

## Simple

There are a set of 'simple' keywords, which are made up of a word:

- styles
    - `reset | bold | dim | italic | underline | blink | inverse | hide | strike`
- undo styles
    - `!bold | !dim | !italic | !underline | !blink | !inverse | !hide | !strike`
- foregrounds
    - `black | red | green | yellow | blue | magenta | cyan | white | default`
- backgrounds
    - `on-black | on-red | on-green | on-yellow | on-blue | on-magenta | on-cyan | on-white | on-default`
- reset
    - `{[]}`

`reset` is a little different than the others in that it is empty.

## Complex

The more complex syntax is entirely reserved for color codes.

Colors are expected to be one of the following,
optionally prefixed by '`on-`' to indicate being a background color:

- `u8` -> `(38|48);5;u8`
- `u8,u8,u8` -> `(38|48);2;u8;u8;u8`

And, prefixed with `#` to indicate hex,
but without any commas:

- `#u8` -> `(38|48);5;u8`
- `#u8u8u8` -> `(38|48);2;u8;u8;u8`

so some example colors could be

- `on-15` -> `48;5;15`
- `15,115,215` -> `38;2;15;115;215`
- `#0f` -> `38;5;15`
- `on-#0f73d7` -> `48;2;15;115;215`
