Color-matching paint at a hardware store is nowhere near as easy as they make it seem in the commercials. There are people who just don't get it. Yes, there is a machine that we use, but 60% of the time the color requires some extra tweaking, and you need a good sense of volumes and colors to do it. I did it for two years and got really good at it, but it was STILL amazingly hard at times.
I've had customers bring in some crazy stuff to match. Like, entire doors, or drawers, or cabinets, when really the only thing that would fit well over the 1/4" hole in the machine would be a paint chip or a medium-sized piece of wood or something. It was ridiculous.
Nevermind matching FABRIC or ROUND objects. It was virtually impossible.
Still, people could never realize just how hard it can be. They think YOU'RE dumb because you have to tweak it AFTER using the machine because it STILL doesn't match. Then there were customers who used to say the color was off when to everybody else it seemed to match, and they would make you continue to work with it regardless of how many other people you had to serve.
You haven't lived until you have to color match 10 consecutive samples of paint.
Thankfully it's been a LONG time since I've worked there. I mean it wasn't terrible, but it was retail.
