I have an Excel program with 1090 color RGB codes. For those interested, please PM with your email and I'll send you a copy. These are good for making any color decal you need; however, I caution you to test this on plain paper before committing color to decal paper (unless you have an unending supply of it, in which case, I want some

).
It is copyrighted, so please do not attempt to claim this for your own work...
