So i'm currently building a home in TS2, and the downstairs colour palette is more bright with colours such as yellow, white and blue.
In contrast, the upstairs is more dark with green, orange and brown

Do these colour palettes work together? Or should I change the colours of the upstairs?

I've also included a picture of the front of the house so you get the general vibe i'm going for!

Hi, this forum is for game problems, probably a better place to put it would be the building forum:

I like the colours, they look good to me! It's really just a question of aesthetics, do you like the rooms and are they what you were aiming for?
