The blue one is pretty cool and I'am using it right now! Otherwise try the black colour if they have one. You can also get the htc one m8! Better body design.
My twin bothers both have them and one has green the other has yellow. They love them but they also have life proof cases that don't draw as much attention to the color because it covers all the edges.
Blue, yellow or white. But the best is a black iPhone 5.
Blue or yellow works for guys
The blue one isnt that bad it isnt girly, their colours for boys n girls. If you get white you could just buy like a case, thats what i did but i bought a coloured transparent case and it looks cool.
I'm a boy and I have yellow, blues a boys colour
blue is not that girly. white is a good colour because you can could put a coloured case on it. thats why i did. everybody was really shocked and thought my phone was that colour
