If I decide to use color in the logo I am partial to blue. I like the blue and gray combination as well. The idea of something all-encompassing is great and the dimensionality of the globe or sphere is also appealing. Green and gray looks too much like XBOX colors. I find red too bold for the look I want to convey.
I like how the color in the images fade but I think it should fade in, not fade out. To me this feels like things are coming apart and we want our clients to believe we bring things together - from many parts to form one system.
I like the smoothness of the font and the all lower case. I also like the tonal balance of the colors between the image and the text, I don't need one to be more pronounced then the other. The size ratio is also very good and since this will be most often used on our vans and letterhead the side-by-side (as opposed to over-under) is preferred.
BTW I always provide all the logo variations (full color on white, full color on black, gray scale, reverse gray scale, etc,...) in vectorial, jpg and transparent png.
I send the changes requested. Just FYI once the contest is in judging mode you can still ask for the revisions to your ranked 1. And you can change your ranked 1 any time you want. Best Regards, Amalia
