Arguments

:: Exp Float	hue component
-> Exp Float	saturation component
-> Exp Float	lightness component
-> Exp Colour

Construct a HSL colour value from the individual channel components. The hue component is measured in degrees and wrapped to the range [0..360), while the saturation and value are clamped to the range [0..1].

clamp :: Exp Colour -> Exp Colour #

toRGB :: Exp (HSL Float) -> Exp (RGB Float) #

Convert a HSL colour to an RGB colour-space value

fromRGB :: Exp (RGB Float) -> Exp (HSL Float) #

Convert a point in the RGB colour-space to a point in the HSL colour-space.

hue :: Exp (RGB Float) -> Exp Float #

Return the HSL-hue of an RGB colour

saturation :: Exp (RGB Float) -> Exp Float #

Return the HSL-saturation of an RGB colour

lightness :: Exp (RGB Float) -> Exp Float #

Return the HSL-lightness of an RGB colour
