how about in this picture,Poportugal said:Bono never used:
Brown ones , color code is H49
There is also a dark blue mirrored ones, H50
These colors are new, he only used G39 and G37
G39 - on cover of book Bono by Bono
G37 - Brooklin bridg show, Vertigo video, All because of you video
And I KNOW IM RIGTH; I HAVE ONE PAIR OF G37
the shades look brown to me. also the frame is darker
I think is not a picture or color effect
