Please help - recent floor tiling job but grey grout instantly turning white

[tjmerwanji]

I live in the sorta Greater London, Wimbledon area. Anyone around?

Also the tiler has left a lot of thick groat near the walls and I have a feeling due to the thickness and size it's not going to change colour, which would make the grout colour different throughout.

I'm not a tiler or anything and I didn't want to seem too fussy to the tiler so just left him to it. Unfortunately it's gone wrong and I'm panicking as can't really put furniture in the house till it's sorted can I?

With regards to the tiling, spacers were used throughout. Does it look bit bent? Can post other pictures if it helps?

Thank you all guys...for someone who's a natural worryer I really appreciate it!

Id wait 2 weeks to let the grout dry
If its still patchy after that im betting the tiler grouted before the adhesive had fully dryed.
