A lot of people, not only Poles, love such stuff. E.g., famous garden gnomes in Germany. I have seen very expensive and extremely tacky things in the USA, too. So , we are not unique. Brits also must have sth similar.
Exactly, grey is a killer of your psyche. Strange that some people don`t realise it.
I agree. During WWII here in the US grey was a popular color for painting the interior walls or woodwork in homes, so it was still in many houses when I was a small child. It made those houses look old and "dated." More colorful trends took over with things like white walls with colored woodwork, then a bit later colored walls with white woodwork.
Now grey is making a come-back here for the interiors of homes. My pet peeve is that baby nurseries are now being painted in shades of grey. Pink and grey combined are very trendy right now! I do not like them! It is reminiscent of the 1950's!
