First of all - TV shows are far from real life. I think it's true for every country in the world.
Acid colors are not typical for russian culture at all.
It's funny coincidence, but yesterday I spent about 1 hour of google panoramic views of England and Ireland. Especially yellow "indoor" dots.
I found England crazy about indoor space partition. And Ireland, imho, is absolutely crazy about color schemes. My brain was almost hurted.
Of course, it was moslty hotels, bars and shops, but anyway it was too overcontrast and overbright. Also, it seems Ireland doesn't know about price labels.

Imho, in comparison with North America (from google panoramic views) russian habits allow "noisy in colors and dirt outside". AFAIK, suburbian houses in North America even required to obey surrounding color scheme. It's not about Russia. Noisy colorful scheme is usual thing outside.
However, usually we do not like "crazy colors" inside houses. It can happen, but I think it's not widespreaded.
