People that run multiple flies, do you use the same color all the way down?

If you're "matching the hatch" or if they are snacking on a GREY rs2, do you tend to have all your flies grey? Or do you like to have different colors on your setup? Idk if it's my OCD but I have to have like green all the way down or black all the way down or grey bottom two or brown bottom two. Obviously they're not eating just one bug so I'm trying to figure out if I need to get over the OCD part of it lol. I normally do pretty good/decent with same color all the way down 🤷
