Color Psychology Cont'd

It's interesting that there seems to be quite a few phone companies that use red in their logo. Docomo, of course, in addition to companies such as Vodafone, Verizon, VirginMobile and Motorola.

I wonder why that is - for the aggressive component. It seems like there's a lot of black and red combinations which are particularly aggressive and bold. Is red more of a tech color? I'm not sure, but it something to consider. I really like the grey in my design, and some sort of pink or electric color would make the company stand out, since so many use red and, if not red, than blue.

I've always liked the Tmobile logo, because it looks different, but still clean and compact.
I'm not crazy about the font, but I enjoy the graphic and the spacing, as well as the color.
