What colour silicone in tiled corners between floor and wall

[MortarThePoint]

One of the two tilers I used doesn't grout corners and leaves it to be siliconed with colour matched silicone. The other tiler didn't, but I am inclined to silicone the corners there too.

 

When the walls are white tile & grout and the floor is grey tile & grout, what is the convention in terms of silicone colour for the joints between floor and walls? I assume I use the same colour silicone as I am using in the wall-wall joints, so white.

 

In another bathroom, I have grey tile & grout on both walls and floor. That leaves me wondering about the joint between the shower tray and the walls (and floor too). Also up the shower cubicle edge strips (chrome).

I meant to say the grout is the same as the tile colours so have now edited it to make that clear. In the first room I mentioned, it's white grout on walls and grey grout on floor. The other room has grey grout all round
