not an easy question. i have been working on lozenge paint colors for years. for one thing the data and knowledge is always changing, getting more refined and accurate so to speak. to my eye the aviattic stuff looks the most accurate but there are those who will disagree. the subject has been debated to death and still variations exist. personally it took alot of work to get upper 5 color, upper 4 color, and lower 5 color mixs which i used the doug baumann data. i wanted to be able to touch up when there was a decal tear or in the case of dougs home printed inkjet decals sometimes if the clear cote wasnt brand new a crack could cause the ink to leach/bleed out giving you white voids. doug doesnt do decals anymore(at least thats what it seems like) and i have since fell in love with aviattic stuff which is similar to dougs stuff albeit better, better quality and colorwise plus fabric texture. perhaps you can download and example of the art even if it has a company logo across it and use that as color chips and then do some mixing. i doubt if there is anything close strait out the bottle, i have 500 or so jars of paint,humbrol enamel,model master enamel and acrylic,tamiya,gunze,polyscale acryl(both red and green label),flouquil enamel, misterkit, testors, i know of nothing i would use strait from the bottle to match lozenge colors. let me know what you end up doing. perhaps i can help in some small way if you get stuck.
