(For the motivation behind the package, please see [the initial announcement](https://discourse.julialang.org/t/ann-domaincoloring-toy-jl-smooth-complex-plotting/102080).)

I’m happy to announce that both DomainColoring.jl and its interactive version DomainColoringToy.jl now have a stable interface! As a notable difference from the initial version (apart from many new extra features and plots) is the added support for Plots as a backend.

These packages implement a suite of plotting functions for complex functions, the primary one being `domaincolor` giving pictures like this illustration of z^3 - 1.

 ![z^3 - 1](https://global.discourse-cdn.com/julialang/original/3X/8/4/844a30265bd0b7dcaf772dfcdbcca46d01788778.png)

The packages have [extensive documentation](https://eprovst.github.io/DomainColoring.jl), designed to be usable in a course on complex analysis (we thus also introduce some Julia basics, enough to get some plots to appear).

Furthermore, there are specific routines to support those with green-red and yellow-blue color vision deficiency, like the following example of e^{1/z}, generated by `pdphaseplot`.

Hopefully, this package can help you in your research and/or studies, or perhaps even pique your interest to the wonderful field of complex functions. To learn more, see [our documentation](https://eprovst.github.io/DomainColoring.jl).
