I agree that the quality of harness is more important than the color of the piping.
We are not trying to infer anything... But a lot of the cheapie harness has red trim, which I think is sending red flags. If you need help picking a first time show harness let us know... We are always happy to help! Just be very, very careful of any harness under $300... They may not last long and be unsafe or not fit your horse comfortably. It is certainly something to save up for... But worth it in the long run.
That said... I don't like red trim and prefer black (the most versatile) or gold on a brass harness or silver on a nickel harness. I did have a harness with metallic purple trim but I've been unable to find another one like it!!!
