material-color-palette

Google's original 2014 Material Design color palettes as a Python library package.

Image showing all shades of all colors. Generated with extras/palette_image.py

Original source (scroll down to 2014 Material Design color palettes and expand).

Because I wanted to use the palette in my projects, but didn't want to copy-paste values, and couldn't find an existing implementation that was simple and complete.

Fully type-hinted and with a test suite.

Installation

Install from PyPI, e.g.:

pip install material-color-palette

Usage

>>> from material_color_palette import Color
>>> MY_COLOR = Color("red", 700)
>>> MY_COLOR
Color(name='red', shade=700, rgb=(211, 47, 47))

# Use RGB triplet representation in e.g. pygame/pygame-ce:
>>> MY_COLOR.rgb
(211, 47, 47)

# Use hex string representation in e.g. Matplotlib:
>>> MY_COLOR.hex
'#d32f2f'

# r, g, b properties should cover any other need:
>>> f"r={MY_COLOR.r/255}, g={MY_COLOR.g/255}, b={MY_COLOR.b/255}, a=1.0"
'r=0.8274509803921568, g=0.1843137254901961, b=0.1843137254901961, a=1.0'

# Accent colours use the original notation, so shade value is a string  
>>> Color("pink", "a100")

# You can use strings for non-accented colours too, if you want to be consistent
>>> Color("teal", "100")

# Useful, contextual error messages:
>>> Color("lime_green")
