Functions ¶
func HslToRgb ¶
Given HSL values (where hue is given in degrees (out of 360°), saturation and lightness are [0, 1]), return the corresponding RGB values (where each value is [0, 255]).
Types ¶
type Color ¶
type Color struct {
// contains filtered or unexported fields
}
func Darken ¶
Darken the given color by a certain percent. Consistent with the results of the Sass darken() function.
func Desaturate ¶ added in v1.7.48
Desaturate the given color by a certain percent. Consistent with the results of the Sass desaturate() function.
func KelvinToColor ¶ added in v1.8.13
Takes a color temperature in degrees Kelvin and returns a valid Color for that temperature. This function works best between 1000K and 40000K.
func Lighten ¶
Lighten the given color by a certain percent. Consistent with the results of the Sass lighten() function.
func MixN ¶ added in v1.7.48
Mix two colors, producing a third. The weight value specifies how much of the first color should be included. Consistent with the results of the Sass mix() function.
func Saturate ¶ added in v1.7.48
Saturate the given color by a certain percent. Consistent with the results of the Sass saturate() function.
func (Color) Equals ¶
Return whether the given color is equal to this one in the 24-bit RGB (RGB255) color space
func (Color) HSI ¶
Return the current color as hue (out of 360°), saturation [0, 1], and intensity [0, 1].
func (Color) HSL ¶
Return the current color as hue (out of 360°), saturation [0, 1], and lightness [0, 1].
func (Color) HSV ¶
Return the current color as hue (out of 360°), saturation [0, 1], and value [0, 1].
func (Color) MarshalJSON ¶ added in v1.8.74
func (Color) NativeRGBA ¶ added in v1.8.73
Return the color as a color.RGBA struct.
func (Color) RGBA ¶
Return the current color as a 32-bit uint quad, implementing the color.Color interface.
