I like the second one the most. I think the two tones are cleverly combined with the question mark and the text clearly stands out from a distance.
The second one.
El diseño del segundo me parece más original porque el signo de interrogación no es tan obvio como en los otros dos.Saludos
I like the green. I think #2 too abstract. The question mark on the green is elegant and clear. And I think the color green conveys a positive, progressive sensibility.
I like the red.
I agree with Pete and like the green one
Thanks a lot for all your comments.Diego
