What colour to paint a tiny shower room

[Uhohmummy]

Help! We have a tiny shower room which is tiled to half height with white tiles, so only has a small wall (behind door) and two half walls (above tiles) to paint. I originally thought of going bold but I think that’s going to look silly as there’s so little painted wall.
Any idea of what colour to paint this room? I feel like it needs some contrast to all the white. The floor tiles are a warm dark grey.

Oh following as I have an ensuite to do and small downstairs w.c and I have been thinking about going a bit darker.

I’ve chickened out and am going to use a stone colour which will be a slight contrast to the white. There’s not enough wall for it to make an impact so I think a dark colour would look strange and bitty. I did love the idea of going for ochre or teal. Let me know what you end up going for Slightly!
