83 KZ550A Red Sticker color code

My "550" sticker has about a dime size piece of the red missing from it which exposes white. I would like to get some sort of red color touch-up paint and do that because the actual 550 has clear coat over it and part of the paint. Any suggestions on which red is most similar?

I would try Testors model kit red paint. or maybe pinstripe tape. If a guy is determined to find a better match, I guess he could get some color sample cards from the home depot, then try to find a good match. or using a good smart phone, take a pic & edit it if necessary so that the color matches the tank. then check the various mfgs. duplicolor. krylon. rustoleum. autozone. automotive touch-up paint. honda. ford. etc. .... 1983 Kawasaki KZ550 Decal Set
