Data.Colour.Palette.RandomColor

Functions to create random colors. Includes a port of David Merfield's randomColor.

A Library for generating random colors.

Choose a random color from CIELAB colorspace.

randomCIELab :: MonadRandom m => m Kolor

Generate a random color from CIELAB (a perceptually uniform color space) with a White point of d65. Probably the best choice if you want a totally random color.

randomCIELabPalette :: MonadRandom m => m [Kolor]

Generate a random color palette using randomCIELab. First choose a random color then choose a random harmony and apply it.

randomCIELabPalette

Choose a random color using David Merfield's algorithm

randomColor :: MonadRandom m => Hue -> Luminosity -> m Kolor

Generate a random opaque color.

randomColor HueRed LumBright

randomColor HueOrange LumBright

randomColor HueYellow LumBright

randomColor HueGreen LumBright

randomColor HueBlue LumBright

randomColor HuePurple LumBright

randomColor HuePink LumBright

randomColor HueMonochrome LumRandom

randomColor HueRandom LumLight

randomColor HueRandom LumDark

randomColor HueRandom LumRandom

Better to use randomCIELab for truly random colors.

randomPalette :: MonadRandom m => Hue -> Luminosity -> m [Kolor]

Generate a random color palette. First choose a random color then choose a random harmony and apply it.

randomPalette

randomHarmony :: MonadRandom m => Kolor -> m [Kolor]

Return a random harmony based on a seed color.

Choose a random HSV component

randomHue :: MonadRandom m => Hue -> m Int

Return a random hue in the range $[lo, hi]$ as a Double. lo should be >= 0 and hi < 360. Instead of storing red as two seperate ranges we create a single contiguous range using negative numbers.

randomSaturation :: MonadRandom m => Hue -> Luminosity -> m Int

randomBrightness :: MonadRandom m => Hue -> Luminosity -> Int -> m Int

Pick a random brightness value given a Hue, Luminosity and saturation.
