That's not really the point, though. Being in the market for a new house I can say that I really have to fight certain biases to look past a home that has hideous color choices (subjectively speaking). I tend to then find more faults in these houses. Houses that are relatively neutral are much easier for me to envision what I'd do with them differently and so I find myself picturing my family living there. As a seller I would want to maximize more of the latter obviously.

Edit: I should also add that since we will be selling our house we recently painted the rooms that were "our colors" to more neutral ones to make it easier to sell.

It doesn't matter, it still shapes the buyer's opinion of the place, even if it's only subconsciously.
