Medium light blue. And you can paint the grout lines off white to make the tile look fresh. Use a grout paint from a big box store.

I have agree with Sophie. I would find the budge somewhere to replace these. These items aren't that expensive to replace.

Even if it's true that you could change sink and toilet, you haven't said that you dislike them, and maybe you can't change them if you're renting.

As for your question, I like Anne's idea, don't know if you're up for such a bold change though. I've just painted my bathroom (walls had been painted dark beige by previous owner) and I went for white, with bright blue stripes on one wall. It's changed the space completely, it's much brighter now. Stripes can make it look bigger too: example here.
