You can colour your text as you like only if it is for your personal reading. You make it less straining when it's for public consumption.

It is true that you can eat whatever you like, but you can't serve the public whatever you want. Rather you'll serve what is generally acceptable.

You can drive any car you want but not a government or military car.

There's freedom, but you don't use it to inconvenience others. I spent almost 30 mins trying to read from this page. The colour hazard is a nightmare, I don't think I'm coming to this thread again.
I would have voted if there's an option like "do what is right"
