color-hash

Generate a color based on a value

This 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 the color-hash Javascript library.

It supports Python 3.7+ and it has no dependencies.

Quick Start

>>> from colorhash import ColorHash
>>> c = ColorHash('Hello World')
>>> c.hsl
(131, 0.65, 0.5)
>>> c.rgb
(45, 210, 75)
>>> c.hex
'#2dd24b'

Installation

Its hosted on PyPI.

pip install colorhash
