For sure I will change the color, I was using this link
http://www.jpsmodell.de/katalog/jpsedw_e.htm as a reference for the Nr. 18. It seemed like a light brown but turned into a pink. I'm not much of a paint mixer, i'd rather just have one color to use. The pattern I was just trying to use that picture of the prototype you showed, but maybe I was too big with it. I think I will repaint with the yellow and do a test paint on one of the panzer I turrets before I do the chassis until I get it right. I do plan to go with the tricolor pattern. Thanks for the comments.
