Green -- #7 and #8 are great, because the the circle/ring seems to accelerate the logo name as it passes through, especially with the color change. This effect works very well. #13 is good too, feel feels unbalanced as compared to #7 and #8, and of course has no color change.
Thanks, green. #8 is still the frontrunner. I'm curious in what other colors do you think this logo would look good?
I ask because I like red (and our old logo is red), but my team is considering to move away from red because of the negative image of red in the financial industry.
