class Color(r, g, b)

Bases: Color

A color as an RGB tuple.

static uniformColor()

Return a uniformly random color.

static defaultCarColor()

Default color distribution for cars.

The distribution starts with a base distribution over 9 discrete colors, then adds Gaussian HSL noise. The base distribution uses color popularity statistics from a 2012 DuPont survey.

class NoisyColorDistribution(baseColor, hueNoise, satNoise, lightNoise)

Bases: Distribution

A distribution given by HSL noise around a base color.

Parameters:

• baseColor (RGB tuple) – base color

• hueNoise (float) – noise to add to base hue

• satNoise (float) – noise to add to base saturation

• lightNoise (float) – noise to add to base lightness

class ColorMutator

Bases: Mutator

Mutator that adds Gaussian HSL noise to the color property.
