Color of the silicone joints in the bathroom?

I have a question for you.....we have gray tiles in the guest bathroom and silicone on the floor in silver gray color.....now the joints around the toilet bowl and the washbasins are still missing....

1. Question: who did that for you, the tiler? The sanitary guy?
2. Question: which color did you use for the ceramics, white, or matching the other silicone joints in our case gray?

Own work

2. Question: which color did you use for the ceramics then, white, or matching the other silicone joints in our case gray?

White, like the ceramics (at least it is also the usual color for the ceramics)

White like the ceramic, otherwise looks strange. Really. The plumber here cooperates when installing the parts.

Also have white.

Even with grey as the most neutral color of all, one can become "fed up" from an overdose.

Gray is not a color, but a psychiatric condition requiring treatment.
