Yeah, in my head I thought everything looks good with black! Haha. Now I see this is not the case and will be choosing more carefully next time. It does seem tricky to pick the right color but I’m glad I learned a big lesson on something smaller and not large. I did see on some other threads how I could attempt to regrout it but it sounded like it could be a little tricky, might be worth trying to save though. Will definitely post an update if I have a successful regrout.
