I feel that if we change the Tan color we will be opening a BIG can of enmity, since 90% of the people building this kit is using Rustoleum Satin Ivory. It might not be 100% accurate but is it close enough? As for the blue, I really like Rust-Oleum Spa Blue: http://www.homedepot.com/p/Rust-Oleum-Painter-s-Touch-2X-12-oz-Gloss-Spa-Blue-General-Purpose-Spray-Paint-249093/100670415
