Color package for the Fōrmulæ programming language.

Fōrmulæ is also a software framework for visualization, edition and manipulation of complex expressions, from many fields. The code for an specific field —i.e. arithmetics— is encapsulated in a single unit called a Fōrmulæ package.

This repository contains the source code for the color package. It contains functionallity to visualize and edit color expressions, and performs operations with colors.

The GitHub organization formulae-org encompasses the source code for the rest of packages, as well as the web application.
