Repair to tile

[Winterhater]

I dropped my phone in the bathroom floor and I’ve just noticed it’s fractured a bit out of a tile so the grey tile now has a white bit showing. It’s only a small imperfection but I’m a bit annoyed and wonder if there’s a way fix this

Could you just superglue the bit that had chipped?

Unfortunately I don’t have the bit that has chipped off

If it's one colour could you try and get a bit of tile grout to match it?

If you mix a little black paint with white grout you could get to a good approximation of your grey.

Or some Fimo modelling clay might work?

Thank you everyone who has replied.
As a temp fix I have applied a bit of nail polish over it which doesn’t make it look as bad and I will look for some grout and paint to do a proper repair.
