Bathroom paint

[nutelladipper]

Hi all,
I'm just having a new bathroom installed. The suite is white with some grey edging. (Very slight). The tiles are shown here in the pic.
The stripes are blues and greys and then darker are a grey. Sorry not a great picture. But it'll be white tiles from floor to the bottom stripe one and then above to ceiling.

I'm really struggling with a paint colour? Would you go grey or pale blue? There is only 2 small walls that will be painted.

The floor is this:

I'd really appreciate your help! I'm 8 months pregnant and going slightly mad.
