The green sky of the Palm Trees Visa Gift Card may bring you up short at first, but when you realize it was done that way using artistic license to create a serene mood, everything is good. Green is the most relaxing color for human eyes to behold, so what could be more relaxing than the dark green palm fronds against a light green sky? (A cynic might say this is the look of a blue sky filtered through a yellow smoggy haze, but we are not cynical.) Relax. Chill. Cool your friends off with Palm Trees Visa Gift Cards.
