Thank you Retina for your fedback! Sure, I can change colors without any problem, but during the judging mode, only 1st ranked designer in your contest can submit new entries. You will need temporary to re-rank designers how could you receive revisions, and later you will be able to re-rank again. I will prepare new variations in next couple of minutes.
Please send variations of blue coloring of the first ranked logo. The top color is good, but we would like variations of the bottom darker blue. No grey please.
