I do not have time to read the code. But if the colors are generated using one way hash, this would be great to have on every site. Using of colors can be replaced by showing the hash in plain text. Everybody would remember their password colors, and typos in password would be history.

That would just be more expensive and less reliable. buttons would do the trick, except for the case you want to have lights on in the moment you are leaving your house.
That was not their duty to do that. they were not on a pay roll, and nobody assigned that project to them. It seems they wanted to do some kind of commitment. Nice to see some people works not just for money, but for a higher good. I wish more people, and not just in software industry, have this kind of motivation.
