I like it. It's a nice change from the old one. Yes, we all got used to the old logo and become very familiar, but I like the colour orange and it's different and unique. Both are good and have their own characteristics, in their own ways.
The way I look at colour blindness, is that is somebody who is colour blind, if they can't see (For example the colour blue) and see blue as green, then they won't know they are colour blind because they see green, which to them they think is normal, but because they don't know what blue looks like, they won't know they are colour blind!
