When hand writing or printing off pedigrees for my dogs I never put any colour on them except black. I think if people really want to know and really want to learn about their dog they will as the OP has done is ask.
I'd rather have people ask then just flash round a pedigree because it has lots of pretty colours on it! One pedigree I saw a while back had working test winners in pink FT ch & FTA winners in green and sh champions in red. Full champions in purple/deep blue colour!
Actually I think I'd just confused by which colour to use! So for accuracy sake I'll stick to plain black!!!! lol
