Take it to the tile store and ask the designer there to help you. It looks like a smoky purple on my monitor but it could be gray or brown

why not paint the room that color and use a white (or white and similar deep maroon) tile for you floor or shower? like this

otherwise, search "burgandy or aubergine tiles)

Zellige tiles may have something in a deep purple like that too

I can't tell what color it is. Beth sees it as a purple which is much nicer than I see on my monitor! :)

Take it to a tile store. Some of the custom tile companies have a huge assortment of colors but you have to seek them out. Pratt & Larson, Heath Ceramics, even Fireclay are good candidates.

I agree with Beth. That's a color that's going to be trendy for a few years and then really out. (It is gorgeous though, I do like it.) Once you grow tired of it, it's so much easier to repaint! Choose a white tile that will look good for much, much longer.

The color looks eggplant-ish to me.

(Oh, why is everything food-ish?)

Green definitely goes with that marvelous aubergine color.

Beth H's great suggestions would be enhanced by a live plant.

You could hang a staghorn fern on the wall, or a big bushy hanging plant from the ceiling, or if that is too boho for you, you could get a live plant for the sink, or even a few stems of lucky bamboo, straignt and curly (which is really dracaena) in a simple cylindrical vessel with pebbles or glass marbles in the bottom.

I put in a new shower enclosure and am trimming it in the tile color for "pop". Thanks for everything. I found a tile shop near me that matches tile!!

Good I guess IMO the fewer finishes in a space the longer you will like them In abathroom my choice is 12 x24 porcealin tile ideally solid color use it fro both bathroom floor and shower walls in a stacked pattern same color smaller tile for shower floor and If you must an accent tile in a strip off center in the shower same tile for vanity backspalsh . Ideally no accent the counter to go with the floor and be done. Then done the road accent color can be as asimple as a new wall color or different towels. No need ever for a POP of color from a permanent material.
