On the website, I chose the blue which was like a powder blue so decided to choose Navy for thread color. I got Royal Blue collar with the Navy blue thread. I love the Royal Blue but would have chosen White thread instead because you can't see the Name & phone # very well. The collar length is the same no matter what size you order so if med, the printing is covered by the buckle. I previously bought an Orange collar with Black thread, which I love but again printing is covered by buckle. Maybe they should figure out how to adjust printing according to size requested so it's clear of buckle.
