You're going to hate me for this... but i've been talking to a designer colleague of mine to get his opinion. He likes the green of #30 better than the blue of #49 and has some compelling reasons for it too.
To quote him: "as far as color goes, you've got a lot of blue going on... but i really like the green accent color. for example on the home page, you have your services "Content Management" in green.... with the logo accent color as green, it would visually relate to those services. so when i'm quickly visually scanning the page, i see green in the logo and green in the services... a quick relationship is built and i haven't actually read anything yet.."
He followed that up with: "it would be nice to see some more ideas similar to #49... something about those floating squares - the big one to be precise - seems a bit off to me. i really can't put my finger on what it is... maybe even play with the concept of "thinking outside the box" since the word "In" is currently in the box... and since it's "inspired" ... makes sense."
Think you can work with that?
(P.S. I still like the squares of #49 better than the circles of #30 ;)
