You're going to have a hard time finding a tile to coordinate with the existing tile. That would be true no matter what the tile looked like. If you put something different next to it it's going to look like you ran out of one kind and finished with another. The only thing that will work is wood. People butt wood up against tile all the time.

I agree with the advice above. You won't find a tile that looks good with your existing tile. Depending on your budget I would look at wood floors or LVP wood-look floors. Make sure you bring samples to look at in your space next to your tile.

Thanks for your recs. What about wood look tile, then ? Another option travertine tile which would mimic the carpetI have now ?

Do they still make the pinkish tile? Do you have any extra pieces of the pinkish tile? Perhaps an inset border of the pink tile with matching new off white tile in the same manufacturer's line would be a good compromise.

I would not call them perfectly good tile . They are really dated and I usually try to not redo something driven by something I dislike . Do you love the tile you have ? If so then go get a porcelain tile that is a color from the old tile or better yet do wood to replace the carpet . I have to say I really dislkke tile for flooring in spaces except for bathrooms.I sure would not do any more of that tile even if you had tons left over.
