I plan to upgrade my floor later this year (fall target). As a result, I've designed about 12 or 13 floors on the RaceDeck website.
I agree with the earlier post that you need to design the floor based on it being fully exposed and open. I personally think the OP's original design is too busy. I also agree that secondary colors from wall decorations, car colors, etc. are all going to add to the overall look.
I want the floor to look nice but not too loud. I already have a nice residential-based epoxy, however due to the way the garage is designed, I am only planning to lay a 26' X 19' rectangle that will cover the majority of the width of the floor and parking areas, while leaving the workbench and the home gym area in the garage with only the epoxy.
As a result, I plan to use only 3 colors in my design; black/tan/charcoal as those three colors match the 3 primary colors in the garage due to the tan epoxy and Gladiator cabinets/benches I have installed.
In the end, do what you want, however a lot of good advise has already been passed on.
