I'm so sorry because I had to withdraw my design in rank 1. I use same concept with other designer (T as '+') that submitted earlier. Hope I can find a better concept in the future.
Thanks for your feedback. I think when we read company name and they are related to color and positive symbol, I'm sure everyone would read the words as "POSITIVE BLUE".
Anyway, I will try to make other variations so "B" is really B as your consideration I will submit it soon.
