@funkeeferret They carry through. If you look at my 25 Cute Street build I tweaked the colors in the first floor bathroom heavily to match my childhood home. Similar to how tweaking skin tones and hair colors work on shared Sims. Otherwise the shades of James Spader's hair wouldn't have been shared properly. And I had spent quite some time tweaking them as well.
A little over a month ago I wouldn't have answered so confidently, but when I lost all my personal builds and had to download them from my EA Studio I got to see them the way others do.
EDIT: Come to think of it, I doubt there is a single build of mine that I have not done this on. Some more than others. Some rather extensively. ALL the tiles in my Romper Rec Playground WoW Edition are completely recolored. Along with the carousel itself, if I remember correctly. It's a large part of how I put my personal "stamp" on my builds.
