Documentation Request - Add comments explaining how color corrections work for color blindness types

[gildurao]

Hello 👋 ,

I've been using your library for development purposes and it's been quite the help to ensure accessibility. I read your source code because I wanted to understand how these color corrections worked, but since there is no documentation, I didn't really get anything.

I also tried checking the library from which you got inspired, but it has no comments on its code as well.

I was wondering if you could add some comments explaining how the color corrections work or just pointing to an external source of information, so that any developer that uses it can learn more.

Best, Gil
