I was thinking of something like this, I would like to avoid replacing the floors . thoughts?

Match the white of the shower tiles.

Look at BM CC-660 Jack pine. It's from the Blue-Green hue family, similar to your third picture. I would also take the shower rod closer to the ceiling.

thanks,what color is the periwinkle blue above?

It’s just a random photo. There are many shades of it and depends how light or dark you’d want.

The photo says SW Aleutian, but that actual color is mor grey than I had in mind.These are some suggestions, but you need to find the one that’s just right.

Oh, never mind - I got that Aleutian color from the wrong photo.

Match the blue in your tile, and then buy a couple of samples. Should be perfect for a boys bathroom. If this is a very young boy, maybe add a few fun accessories when you are done painting it.
