## Visualization
From [https://regexper.com/](https://regexper.com/).
## Usage
It always matches 1, 3, 4, or 5 unnamed groups.
### 1
This group will be the name of the color alias such as `red` or `papayawhip`.
### 3-5
These groups are the color type, then the color values.
OR
These groups are `"color"`, the color type, then the color values.
### Usage
Just filter out the undefined values and you'll have an array of the values you want.
```js
"rgb(255, 255, 255)".match(regex).filter((item, i) => i > 0 && item != null)
"color(display-p3 1 1 1 / 1)".match(regex).filter((item, i) => i > 0 && item != null)
```
## Why?
For fun and to demonstrate Pomsky's power of making complex regular expressions that are still readable.
