No pics will help. Go to a paint store. Nobody else has YOUR bath, your light, your tile, your vanity, your flooring, your light or lack of light ........... your anything.

@JAN MOYER while I agree with you, it is sometimes helpful to see various pix for inspiration and to THEN go to the paint store and get some chips to view in home.

Not much help, but I am convinced that blue is the hardest color to choose. Why? Because it exists in so many shades.

I agree that you should go to the paint store, but don't rely solely upon tiny chips. Once you choose your paint, buy a bitty can and paint a big swatch on your wall -- it's just paint, and if you're unhappy, it's an easy fix. Yes, it adds another step, but often colors look different when you see "the whole picture".

Blues are really hard to work with IMO. I actually like watery colors in bathrooms maybe if you post a pic of the space and give us some reasons behing blue as a choice we could be of more help. I also agee that a large sample board painted with 2 coats is the best way to choose a color in your space .

Vermont slate? I’m going to paint a small powder room this color.

PS. If you find the color paint name and search for it in Houzz you might get rooms painted that color. That is super helpful to me.

I have two blue baths and one dark grey. Here are my blue baths. First one is Greenwhich village a blue that in some lighting can lean grey by behr.

This color looks blue in the natural day light but changes to grey at night.
