# Golang Color Package

Provides several types for representing linear RGB and OkLab colours, compatible with the standard [color package](https://pkg.go.dev/image/color).

The types in this package use float64 components and are definitely overkill - you don't need 192 or 256 bit colour. Probably.

There are two main groups - the *linear RGB* colours, ideal for compositing; and the *OkLab* colors, ideal for comparing colours or for creating visually pleasing gradients.

## Installation

```bash
go get smariot.com/color
```
