Package: colorhash
color-hashGenerate a color based on a valueThis module generates a color based on an object, by calculating a color value
based on a hash value for the object. This means the result is deterministic:
the same value will always result in the same color (so long as the hash
function remains deterministic).This module is a port of thecolor-hash Javascript library.It supports Python 3.7+ and it has no dependencies.Quick Start>>>fromcolorhashimportColorHash>>>c=ColorHash('Hello World')>>>c.hsl(131,0.65,0.5)>>>c.rgb(45,210,75)>>>c.hex'#2dd24b'InstallationIts hosted on PyPI.pipinstallcolorhashAdvanced usageYou can influence every aspect of final color.Default valuesare following:ColorHash(obj:Any,lightness:Sequence[float,...]=(0.35,0.5,0.65),# picks 'randomly' onesaturation:Sequence[float,...]=(0.35,0.5,0.65),# picks 'randomly' onemin_h:Optional[int]=None,# hue, min 0max_h:Optional[int]=None,# hue, max 360)But be careful,setting tight conditions may result in very similar colors. See example tables.You can fix lightness or saturation to single value(s) by using sequence with 1 element (eg.[0.5]).codehexcolorColorHash('hey')  # default#782d86ColorHash('hey', lightness=[0.55])#b453c6ColorHash('hey', lightness=[0.75])#d69fdfColorHash('hey', lightness=[0.95])#f7ecf9ColorHash('hey', saturation=[0.15])#8d6c93ColorHash('hey', saturation=[0.55])#b139c6ColorHash('hey', saturation=[0.95])#d406f9ColorHash('hey', lightness=[0.95], saturation=[0.95])#fbe6feColorHash('oh', lightness=[0.95], saturation=[0.95])#fef0e6ColorHash('boi', lightness=[0.95], saturation=[0.95])#e6fee7You can set hue range or even fix it by settingmin_h=max_h.codehexcolorColorHash('hey', min_h=150)#2d5886ColorHash('hey', min_h=300)#862d6cColorHash('hey', max_h=150)#866e2dColorHash('hey', min_h=150, max_h=360)#2d5886ColorHash('hey', min_h=150, max_h=150)  # fixed hue#2d8659Or you can letColorHashdecide between combination of manylightnessandsaturationoptions (mindmin_handmax_hare equal in this example).codehexcolorColorHash('stick', min_h=65, max_h=65, saturation=[x/10 for x in range(1, 10)], lightness=[x/10 for x in range(1, 10)])#869108ColorHash('with', min_h=65, max_h=65, saturation=[x/10 for x in range(1, 10)], lightness=[x/10 for x in range(1, 10)])#eef5a3ColorHash('one', min_h=65, max_h=65, saturation=[x/10 for x in range(1, 10)], lightness=[x/10 for x in range(1, 10)])#ddeb47Finally some bad examples.
