First the boys colored a tabernacle. It was a basic house shape with a cross on the top and angels at the sides. 
Even my 12yo colored one.
I often hear from people that their boys "hate" to color. My boys are mostly okay with it. They love to create, so they are usually agreeable to the process. They do like to use fine tip felt markers for outlining- it gives the project more of a finished look.
