I'm a sucker for the neatness of the square.

My dear departed mother was never much of a drinker but every Christmas morning the two of us would have some form of champagne cocktail. Often a Mimosa, which went down a treat. BUT the year we tried a champagne and strawberry liqueur mix was a disaster. Well not for mum and I, we giggled through until mid afternoon when crashed for a nap. When we woke we realised the peas went unserved, some people had the wrong presents and there was something very charred in the oven. The family still talks about the year we were too tipsy to cook lunch. This year it'll be straight champagne (and after 8 years I still miss her dreadfully).

Thank you for some concrete information. Those samples could actually be different batches of the one colour. The flecks and shading are almost identical. Is the new version the low silica option following legislative changes? If so, you’ve been caught up in a change that was beyond the Manufacturers and your control. It would also explain the same name being used, something typically not done because it causes problems. PS you assumed I’m a guy. I’m not but I do have 25+ years of dealing with contracts, vendors and projects. Half my life is spent trying to get suppliers to do things they may not want to do, and it all comes back to the paperwork particularly the disclaimers and exclusions. I can’t see any resolution for you.

Personally I'd be very careful adding stacked stone next to the dark bricks. I think stacked stone can work next to rendered areas to provide contrast/add another element but next to dark bricks it could easily look too busy/too much. It's your home though so do what will make you happy when you drive up to it! If you're dead set on the stacked stone then find the brick manufacturers location and ask to speak to one of their designers for an opinion/options. If they can't help then ask brick manufacturer for the addresses of some properties in your city that have used your particular brick and check a few out. They will usually give you some addresses if you explain what you're trying to do. I'm sorry to have not answered your question as to what colour stacked stone to use. Good luck, exciting times for you.
