I like your thinking about seeking fixture colors that are paler versions of some of the truly period mid century colors. As the owner of a pink bathroom, I've polled people for years, and I think some retro colors are a little hard-core for most modern homebuyers...except for a brave sliver of the population who love them dearly. I wondered about pale gray fixtures, coupled with a pastel tile in one of the colors you described (perhaps tile accents/borders in a pale gray, to tie in the fixtures?) Are any nice fixtures available in soft grays? I read an article not too long ago about how popular gray was, as a wall paint color, in the 50's-60's. Maybe a creative (over the top?) approach with pastel colored tile would prevent you from having bathrooms that felt boring to you. It's no fun to spend lots of money and not be excited with the results, so I sympathize. No wonder you are frustrated.

We often leave doors open. This is why I wanted a dutch door but they were too expensive and we are not crafty enough to convert a door. We also let our old horse, goats, chickens, ducks etc wander about property and destroy all attempts at landscaping. (used to have a bottle lamb that came in house looking for me and checked the doors sounds cute but they don't housetrain - gross) My horse will go inside anywhere garage, shed, chicken coop for chicken food. He puts head inside windows left open in cars and trucks he'll check for crackers, chips, bread, and some fruit but not apples- weirdo. On one of his foraging trips just inside kitchen door he slipped a bit and rammed down on one tile that cracked. He is not invited in but he watches doors. Animals are now locked up when parties and bbq are thrown as they forget they are livestock and get pushy and graze the appetizers which is really the dogs job. kinda funny I suppose if you are not used to it, but predictably irritating if you know better and let them out to find your garlic bread gone. So my need for impervious flooring - mini farm. I did use our dirt when selecting colors too!. thanks for all the help I couldn't think of how to finish entryway on a budget but these ideas help.

Instead of looking for ads for an extra box, I'd suggest creating your own ad. I think you can advertise for things you want to buy on Facebook marketplace. There might also be buy/sell sites on Facebook for your area (look for your county or city buy sell). I'd start there and branch out. You might also try Craigslist although I'm leary of that site in general. If it was sold in your area, someone might have an extra box they'd be willing to sell. Have you contacted the manufacturer? They might be able to provide a suggestion.

Sorry I wrote in the wrong product name. The original was Roma beige 24 x 24. This is going in a living room in front of a sliding glass door. The problem has arisen because there were plantation shutters here which have been removed and the tile had been cut around the base of those shutters so we have 4 tiles that need to be replaced. In the photo, the lighter tile is the original Roma Beige. The darker tile against the wall and slider is the Roma 2.0 Spice.
