COCO (Color Converter) for Go

COCO (Color Converter) is a color conversion library for Go. Heavily inspired by NPM's color-convert. It converts all ways between rgb, hsl, hsv, hwb, cmyk, and hex strings.

Install

Just run this:

go get github.com/hisamafahri/coco

Usage

coco.Rgb2Cmyk(140, 200, 100) // Output [4]float64: [30 0 50 22]

// RGB to HSL
coco.Rgb2Hsl(140, 200, 100) // Output [3]float64: [96 48 59]

// RGB to HSV
coco.Rgb2Hsv(140, 200, 100) // Output [3]float64: [96 50 78]

// RGB to HWB
