The library creates colors according to this system:

Wow @MovGP0 this looks really cool. It will take me some time to get it reviewed. But thank you for it.

@Keboo I was trying to keep the implementation as close as possible to the original implementation.

However, this has also has some drawback we should consider:

1. colors are represented as signed 32bit integers, instead of System.Windows.Color. While a conversion is easily possible, the question is if we only should use a conversion at the border of the library, or also replace int with Color for internal usage and break with the original source.
2. the unit tests don't have a 100% coverage and have multiple asserts per test. While this makes it aligned wtih the original source code, I'd consider it bad practice to structure unit tests like this.
3. the CS0618 warning is on purpose, since this is how it's in the original code. The question is if this code should be removed or the warning suppressed.
