To adjust my first comment : colors could be red, orange, pink, purple, green, yellow... Avoid blue or any "French blue white red" colors. Feel free to come back to me for more precision.
Hi CH, I am terribly sorry could not spare much time designing for you. My little sister is getting married this Sunday, this event is keeping me busy this week, so I may not be available till Monday. But once a while I will try to monitor this contest progress. You may criticize every designers designs, every feedback you provided would help to accomplish your need for your new company logo.
