It appears they white washed it but chose to not address the grout.

You might be able to strip it or even sand off the paint with an electric sander. Easier to color wash over it. You might want to match the hearth colors. On half of your fireplace I lightened the mortar lines and then applied some colors over it.

You can use any variety of colors, thin the acrylic paint down with water, and apply with either sponge or brush to get the desired effect. Lots of YouTube Videos about this.

I think I need to see the whole space to advise anything. I do not think removing this will be easy so in most cases either a heavier whitwash including the grout or painting it .

either paint the grout white or paint the whole dang fireplace a solid color. can I see more of the room and then I could virtually paint the fireplace

Perhaps it’s the brick look itself that troubles you. Have you thought about tiling over the brick with a tile that better coordinates with your flooring.

Thanks for all of the suggestions thus far- very much appreciated!! I added an photo that is zoomed out a bit more.

What are you planning to do with the hearth? It looks a bit large/tall compared to the actual fireplace surround.

I'd paint it white for you but it doesn't change much from what you have. You could get a solid looking white though if that is what you wanted.

I like Melissa R's suggestions. Good look and far easier than trying to get rid of the whitewashing. I would paint the sides of the hearth also.

Great suggestions- thank you! It’s helpful to see the edited photos, much appreciated!
