Which to Choose, What to do

I'm still trying to figure out how to best incorporate the block elements with a burst of color. It made sense to do something with the "n" in "Denwa" since it splits the word in half - thinking of how Docomo often plays with pairs of letters in their even-number-lettered name. Anyway, here are some samples:

I think it works better with one colored-pink letter, because three blocks distracts from the word. The embossing is also preferable because it compliments the strong pink better than the lighter gray, though both go with pink. I think the block colors and the pink in the "n" is what I like best. I also tried other fonts for the "mobile phone company" text, but I like the original best. Gothic was a close second. So that's where I'm at now.
