1) Do not ever try and use computer generated images as accurate color sources if you are trying to aim for accuracy. There is too much variation between monitors as well as between monitors and printers. If you're just out to have fun, be my guest, but if you're aiming for accuracy your monitor and printer cannot be trusted for color accuracy.
2) If you're referring to posting problems on ModelWarship drop me a line here or there. The owner of ModelWarship implemented a rule to cut down on spam that essentially means your first three posts have to be manually approved, but after that you're good to go. Sometimes it might take a couple of hours for a mod to make it by and approve your post.
