## Style Strings
Style strings are a list of words, separated by whitespace. The words are not case sensitive (i.e. `bold` and `BoLd` are considered the same string). Each word can be one of the following:
- `bold`
- `underline`
- `dimmed`
- `bg:<color>`
- `fg:<color>`
- `<color>`
- `none`
where `<color>` is a color specifier (discussed below). `fg:<color>` and `<color>` currently do the same thing , though this may change in the future. The order of words in the string does not matter.
The `none` token overrides all other tokens in a string, so that e.g. `fg:red none fg:blue` will still create a string with no styling. It may become an error to use `none` in conjunction with other tokens in the future.
A color specifier can be one of the following:
- One of the standard terminal colors: `black`, `red`, `green`, `blue`,
`yellow`, `purple`, `cyan`, `white`. You can optionally prefix these
with `bright-` to get the bright version (e.g. `bright-white`).
- A `#` followed by a six-digit hexadecimal number. This specifies an
[RGB color hex code](https://www.w3schools.com/colors/colors_hexadecimal.asp).
- A number between 0-255. This specifies an [8-bit ANSI Color Code](https://i.stack.imgur.com/KTSQa.png).
If multiple colors are specified for foreground/background, the last one in the string will take priority.

### Style Strings
Most modules in starship allow you to configure their display styles. This is done with an entry (usually called `style`) which is a string specifying the configuration. Here are some examples of style strings along with what they do. For details on the full syntax, consult the [advanced config guide](/advanced-config/).
- `"fg:green bg:blue"` sets green text on a blue background
- `"bg:blue fg:bright-green"` sets bright green text on a blue background
- `"bold fg:27"` sets bold text with [ANSI color](https://i.stack.imgur.com/KTSQa.png) 27
- `"underline bg:#bf5700"` sets underlined text on a burnt orange background
- `""` explicitly disables all styling
Note that what styling looks like will be controlled by your terminal emulator. For example, some terminal emulators will brighten the colors instead of bolding text, and some color themes use the same values for the normal and bright colors.
