Types

type Color

type Color struct {
	R float64
	G float64
	B float64
}

func Hex

func Hex(scol string) (Color, error)

https://github.com/lucasb-eyer/go-colorful Hex parses a "html" hex color-string, either in the 3 "#f0c" or 6 "#ff1034" digits form. It also parses the named colors from the CSS3 specification.

func Hsv

func Hsv(H, S, V float64) Color

https://github.com/lucasb-eyer/go-colorful Hsv creates a new Color given a Hue in [0..360], a Saturation and a Value in [0..1]

func HueOffset

func HueOffset(col Color, degrees int) Color

https://github.com/muesli/gamut

func RGB255

func RGB255(r, g, b uint8) Color

Convert RGB values to a Color struct.

func UnsafeHex

func UnsafeHex(scol string) Color

!WARNING! Only use this if you are sure the color is valid.

func (*Color) Complementary

func (col *Color) Complementary() Color

Get the complementary color struct.

func (Color) Hex

func (col Color) Hex() string

https://github.com/lucasb-eyer/go-colorful Hex returns the hex "html" representation of the color, as in #ff0080.

func (Color) Hsv

func (col Color) Hsv() (h, s, v float64)

https://github.com/lucasb-eyer/go-colorful

func (Color) RGB255

func (col Color) RGB255() (r, g, b uint8)

https://github.com/lucasb-eyer/go-colorful Might come in handy sometimes to reduce boilerplate code.

func (Color) RGBA

func (col Color) RGBA() (r, g, b, a uint32)

https://github.com/lucasb-eyer/go-colorful Implement the Go color.Color interface.

func (*Color) Triadic

func (c *Color) Triadic() []Color

Triadic returns the triadic values for any given color
