Basically, you should not necessarily switch styles in a small space. So if you want to furnish a small apartment, besides "less is more," a harmonious overall color scheme is better, because then everything looks more spacious. Gold is currently a trendy color... it would be cool if you picked up the theme in every room with one element (for example, a gold bathtub, gold handles in the kitchen). But gold can have exactly the opposite effect on you in 5 years because it is overlooked. I would rather distribute the trendy colors on the walls: bathtub in white, but in front of a gold wall, the same in the kitchen (instead of the handles). The brain is more flexible and consistent when it comes to shape ;)
