The new rainbow name feature

Firstly, I just want to say how much I have enjoyed seeing people's names come up in a rainbow of colours. What a very cool effect. That being said, when someone's rainbow coloured name keeps appearing in chat, it makes chat quite a bit more difficult to read, due to the constantly changing colours. With that in mind, I would like to suggest that the daily rainbow should last for maybe an hour, rather than the entire day. Or, alternatively, have it last the full day, but only once a week. In this way, chat will remain readable the rest of the time, and the lovely rainbow effect will remain special as it isn't seen constantly.
