Honestly, mixing patching compound to match old concrete is tough. Tbh, I added a bit of gray pigment and it blended in really well. Ngl, the client was thrilled. What's your go-to method for color matching? Any products you swear by?

I can't believe you see any art in it at all. Maybe you're being too hard on yourself or too kind. Either way, it's shocking to hear.
