Feature: adding Green, Yellow, Red to emphasize scores

I also think it is another good feature if we can change the scores' text colours to, let's say, for AAA you get #22C55E green, and for AA you get #FACC15 yellow, and for Fail you get #EF4444 red.

What do you think?

Oh, and also I think it would be great to save the light/dark background colours in localStorage so users can access them easily next time using the website?

I'm not sure about this one, as black and white have fairly good contrast against the background which might be lost by changing to RGB, making the scores difficult to read.

Localstorage implementation sounds good though!
