This arrangement creates a similar type of vignette. The piece of furniture is the first element. Since it is a fairly bright color, the homeowner has used neutral decor on top. Then there is a very colorful painting to continue the look.
The other two elements are so colorful that this vignette needs neutral decor to make this work.
Blue and green are soothing colors, And neutrals used as tabletop decor are a balancing act, to lend a sense of serenity to this space.
This arrangement borders on looking cluttered, but seems to work because of the way everything is arranged.
I find it to be very relaxing.
