Overview

Package basiccolor provides functions to determine the closest basic color (e.g., red, white, orange) to a given color.

Index

• Variables
• type Color
  • func Closest(c color.Color) Color
  • func (i Color) String() string
• type HSL
  • func (c HSL) RGBA() (uint32, uint32, uint32, uint32)

Variables

var HSLModel = color.ModelFunc(func(c color.Color) color.Color {
	if _, ok := c.(HSL); ok {
		return c
	}
	nrgba := color.NRGBAModel.Convert(c).(color.NRGBA)
	h, s, l := nrgbToHSL(nrgba.R, nrgba.G, nrgba.B)
	return HSL{h, s, l, nrgba.A}
})

HSLModel is the color.Model for the HSL type.

Types

type Color

type Color int

Color represents a basic color.

const (
	Red Color = iota
	Orange
	Brown
	Yellow
	Green
	Blue
	Violet
	Pink
	Black
	Gray
	White
)

func Closest

func Closest(c color.Color) Color

Closest returns the closest basic color to c.

func (Color) String

func (i Color) String() string

type HSL

type HSL struct {
	H, S, L float64
	A       uint8
}

HSL represents the HSL value for a color.

func (HSL) RGBA

func (c HSL) RGBA() (uint32, uint32, uint32, uint32)
