description board second plan

After think carefully about the first colorful description board design plan, I worried if it has too much colour. Look at the real EXPO place, I was sure about the first plan is not suit for now. So, I made a change of background colour. I use white colour which is the wall colour of exhibition to be most of background colour, but at the same time, I also kept orange, blue and rainbow these colour elements in the second design plan.
