the new wallet designs seems to destroy the Gems feel for me . the color should still be the salmon pink because that is what Gems has established and most of the people really like that style and if you want to add more color options for users, it should be bright and "happy", but not bland.
but if i had to choose, i like the third one the most on upper right and maybe it would even look pretty good without the blue, but i want to add that you have to keep everything very minimalistic because if it feels even a little complex to some bitcoiners, think about how new users with no understanding of crypto will feel...
maybe it's possible to enable the advanced features from settings to not overcrowd the wallet?
hope you understand
