Earlier quoted context omitted.
The rational explanation why the majority of items are neutral tones/grey is because this maximizes the market. This can be seen on automobiles, where silver is the most common color because it’s easier to sell second hand, so manufacturers learned to optimize for this.
Yes exactly. When choosing colors or amenities for my home, my real estate agent and contractors would bristle — "that's not going to be good for resale value" This has impacts on the industries surrounding as well. If I want a custom siding color, it's going to be more expensive. We're normalizing everything around the most widely palatable, so it's all fairly bland.
My counter argument to this is that then it is the "norm" and society conditioning our taste and dictating what's palatable.
This goes as deep as influencing and forming our sexuality. We get aroused by things that would've not aroused people centuries ago, the canons of beauty themselves changed a lot.
