I was about to sell my greige city. I had regrets and pulled it down before it sold. I took another look at the marbling and color and thought I might not find another that looked quite the same. So I guess there definitely would be people who sold a unique color and could not find another the same -- or had to pay more to replace it after having seller's remorse.
i almost sold my magenta city. i had an option to let go magenta or pictachio, although people said that i should keep the pistachio because it's rarer, i eventually kept my magenta, and not intending to sell it anytime soon
it's so pretty & brighten my mood when i wear it!
