Mr Hobby Color to Testors Color

Jonathan-try this.  Click on the approriate FS 595b std (enamel or acrylic) and hopefully this will help.  There is also a color conversion chart buried somewhere on the IPMS Stockholm web site, but I'm not sure where.  You may want to post on the Paint & Airbrush forum also.

Hooah Sgt!  I see you are also an MP.  I was, then I switched to aviation.  I'm very fond of Ft. Rucker, hell of a lot nicer than Leonard Wood.

Anyway, here is the link for the gunze Sangyo chart on the IPMS Stockholm website.

I prefer this site.  http://www.rlm.at/cont/thema02_e.htm     They have every paint brand there.  you can download the individual sections.  Although its not exactly a conversion chart, it allows you to look up the color code on one chart, then search for the color on another chart.  It helped me tons on my special Hobby Ro. 57bis
