I think they're missing the mark with the blue and orange rings on their keyboards. Just make them black and if you want to offer color options do it in the form of colored-LED lighting or lower the price and leave white LEDs as the only option. My 710+ is excellent from a functionality standpoint (and far from silent), but ugly as sin. Orange, black and gray. The color scheme matches almost no one's PC and borders on obnoxious.
Now they make one with a blue ring? Just leave the ring out of it Logitech. It's not necessary.
Lol- just goes to show, everyone has an opinion. I Just found out about this keyboard and am now returning my g710+, but the ONLY thing I'm unhappy about is losing that color scheme... I would have normally agreed with you too, but with my new desktop build everything inside is mostly black and yellowish orange, plus I have the steelseries rival mouse with black/orange, so it all just goes together. I didn't really plan it like that, and wouldn't usually select those colors if I had cared but when it all came together it does actually look cool to me.
Throwing some random blue in there won't really go together, but I'd rather have the blue keys. I grew up with an IBM, and just miss that strong tactile feedback. If the browns FELT the same but were just quieter I'd be fine with this, but the feedback just feels more natural with the blues to me.
