There is also some evidence that yellow light causes nearsightedness, so be careful with that.

Really? Do you have any sources/links so I can read more about that?

It's summer in Norway here so it doesn't really get dark before my bedtime tonight, but here are some really short videos from a party a couple of months ago: https://goo.gl/photos/PKyzv8HkCyVJSdzv7 Normally I have it set to a static color or a very slow and smooth fade, not the crazyness seen in the vids. Here's blue, which is totally dark with the Uvex glasses: https://goo.gl/photos/SCrU1PhbDmCuPi22A

I love that blue! So what's the cost for that type of a setup?

Probably below 40$ for the whole shebang. It's this, just with an additional 5 m strip and a power adapter: http://www.aliexpress.com/item/10M-3528-RGB-LED-Strip-Waterp...

Wow, that's cheap. So the blueness in the entire room is emanating from the bright spots along the roof?
