# Priduck Color Theme
_A CLI for generating a tri-color theme based on a single hue and an even rotation around the color wheel._
Priduck (name is nonscense) is a color theme originally designed for [Fedran](https://fedran.com) where the base color is a hue (in degrees, 0-360) with with nine colors based on an even distribution around the wheel with nine-levels of brightness ranging from a near-black to a near-white.
## Installation
This tool is currently not available on npmjs. To install it, modify your project's `.npmrc` file to include:
```
@priduck-color-theme:registry=https://src.mfgames.com/api/packages/priduck-color-theme/npm/
```
Once that is done, the CLI can be installed as a development package with `npm`:
```shell
npm install --only-dev @priduck/cli`
```
Once installed, this will produce a CLI in the `node_modules/.bin` folder called `priduck`.
## Commands
### "css variables [--hue HUE] [--output PATH] [--selector SELECTOR]"
Generate a CSS file using variables. The thirty colors all follow the pattern of `--color-priduck-cXbY` where `X` is a number between 0 and 9 (inclusive) and `Y` is the brightness (also in the range of 0 to 9, inclusive).
All of the colors are calculated based on the variable `--color-priduck-hue`, which is not included by default. If `--hue` is provided with a number between 0 and 360, then `--color-priduck-hue` will be set to the given color.
If `--selector` is included, the colors will be wrapped in a selector and slightly indented:
```css
// priduck css variables
--color-priduck-c0b0: lch(5.0 50.0 calc(var(--color-priduck-hue) + 0));
--color-priduck-c0b1: lch(15.0 45.0 calc(var(--color-priduck-hue) + 0));
```
```css
// priduck css variables --selector ":root"
:root {
--color-priduck-c0b0: lch(5 50 calc(var(--color-priduck-hue) + 0));
--color-priduck-c0b1: lch(15 45 calc(var(--color-priduck-hue) + 0));
}
```
### "palette gpl --hue HUE [--output PATH] [--secondary 5] [--tertiary 8]"
Generate a GNU Imp or Inkscape file. `--hue` is required in this situation. This assumes up to two additional colors (secondary, and tertiary).
Both of these are numbers in the range of 0-9 with 0 being an identical color to the base hue (which is always 0).
## Debugging
The CLI uses [debug](https://github.com/debug-js/debug) for logging and (relatively) minor output. The CLI will produce no output unless the `DEBUG` environment variable is set, such as:
```shell
export DEBUG="*"
```
