Color handling made simple.
Project description
Chroma
Chroma is a Python module for handling colors with ease.
Manipulating colors can quickly escalate into a tedious and complicated task, particularly when you become concerned with color systems beyond RGB. Chroma is here to provide a simple API to do the heavy lifting, so that you can stay focused on the important parts of your projects.
Before you ask, Chroma is BSD licensed, available on Github and PyPI.
Features
Hex (#rrggbb, #rrggbbaa)
RGB
HLS
HSV
CMY, CMYK
Alpha
Color Blending: additive and subtractive mixing
Roadmap
Coordinates (sRGB, YIQ, CIE, LAB and more)
Color harmonies: complementary, analogous, triad
Color difference
Color detection in images
Quickstart
Getting started with the power of Chroma is meant to be straightforward
import chroma
# Create a color object
color = chroma.Color('#00FF00')
# Handling different color systems
color.cmy = (0.3, 0.7, 0.8)
color.rgb # (0.7, 0.3, 0.2)
color.hls # (0.0333, 0.45, 0.5556)
# Alpha
color.alpha = 0.5
color.hsv # (0.03333, 0.7143, 0.7, 0.5)
# Color blending
color + chroma.Color("#FF00FF")
# #FF4DFF
And there you have it. The documentation describes Chroma’s functionality and usage in detail.
Installation
Installation is as easy as
pip install chroma
Or if you’re an easy_install-er
easy_install chroma
Chroma does not yet support Python 3, but, if you’re interested, contribute!
Contribute
Chroma is under active development and could use your support. Even bug reports, feature suggestions and feedback can help push Chroma forward in the right direction.
Chroma is hosted on Github and there are a number of ideas of where to start in the issues section.
