More walls and floors option for The Sims 4?

You know how in the base game there are wallpapers that have every single colour ever but I fell they need a few more colours. BUT I want another one with JUST the base board, not plain, not with the huge panelling at the top. There is one in the base game but it doesn't have much colours and the base board changes colour with the different swatches. I want a plain wallpaper with the darks, the standards and the pastels versions but with a plain white base board. It's so simple and I'm surprised that this isn't in the game after 10 years.

i agree, more colours got added last year and this year if not mistaken but i don't think each walls and floors have every colour
i want like each walls and floors type, the fantasy and the realistic one and base board walls and i want each colours for especially the realistic walls and floors, not gonna lie

i love your ideas about the walls and i feel the same way
