You may have a tough row to hoe. I can think of a lot of competitors that have had similar color schemes -- Massey-Fergusun and International Harvester in the agricultural equipment manufacturing sector having similar reds; McDonald's, Burger King, Wendy's, and other fast-food chains having similar yellows and browns. You would have to show that the consumer of the product identified the product by the color scheme and I think you would have to show that the similar color schemes could cause confusion among the consumers.
