Although you can apply colors to the corner glass table, when you exit and re-enter your condo, the color goes back to white, and if you try to edit the color again, it stays white. The only way to fix this is to stash and place down the item again, and that only applies until the next time you load your suite.
Same thing happens to the coffee mug and the coaster.
I’m sure it’s a known bug 
Two of the outdoor lights does this too.
