Aruba Blue.... closer to Denim, Ocean, or? I'm liking this one the most.
Looks like Lava Gray is the new dark gray replacing Dolphin. I think it's got some purple in it, which is a negative. I am surprised they kept Dakar Beige. Maybe it's more popular in Europe. Sphere Blue looks interesting. Of course some of these might not make it to the U.S.

Also from the paintchips I've seen of the TT Ice Silver is far more metallic looking than the old standard Light Silver metallic making it look overall darker than Light Silver.

Aruba looks like the new Night Blue.
