Great color choices. Red Yellow and Blue are the primary colors and will always look good no matter what color is the current rage. When I bought my new boat I had 18 colors to choose from and I also went with the same three colors you have chosen. The boat is 7 years old and people still think it is new because it looks fresh.
I also agree with Troutly that you need to get some blue up on the engine hatch area.
Overall AWESOME layout--I am jealous!!
Please post some pics when it is real!!!
