# color

A package for converting from RGB to HSB and back.

* HSB stands for Hue, Saturation and Brightness

* RGB stands for Red, Green and Blue

## Example usage

![example](img/hue.png)

The above image was generated by the following program:

```go

package main

import (

	hbscolor "github.com/xyproto/color"

	"image"

	"image/png"

	"os"

)

const (

	w = 512

	h = 512

)

func main() {

	// Prepare an image surface

	surface := image.NewRGBA(image.Rectangle{image.Point{0, 0}, image.Point{w, h}})

	// Generate an image that shows a smooth transition over all 360 degrees of hues

	for y := 0; y < h; y++ {

		for x := 0; x < w; x++ {

			c := hbscolor.NewFromFloats(float64(x)/float64(w), float64(y)/float64(h), float64(y)/float64(h), 1.0).RGBA()

			surface.Set(x, y, c)

		}

	}

	// Prepare the image file

	imageFile, err := os.Create("output.png")

	if err != nil {

		panic(err)

	}

	defer imageFile.Close()

	// Write the surface to file, as a PNG image

	png.Encode(imageFile, surface)

}

```
