I love the colorful buildings!
But... the rabbit holes do not match your theme. If you plan on using the RHrugs, you can go crazy and build your own stylish buildings or find some lots that others have created to share with the community.
Floraflora over at MTS has some very nice, deco style community lots - http://modthesims.info/d/573389/old-l-a-art-deco-nightclub.html
