Maybe we need to take something like #67 however and make the "g" in "gisteo" small here so it competes less with the "G" icon. You know what I mean? The icon is upper case and forms a "G" while the rest in lower case...
OK- we're getting close here. How about 90-91 with the slightly brighter/lighter green and more glass like in 64/65?
I personally like 91 better than 90, however, I'm worried that people might have a harder time understanding that this is a "G" on this one? What are your thoughts?
Perhaps play with the "play" symbol a bit on this one- outline it in black to help clarify?
