Why is the lonely tone always blue?

The color of loneliness is always blue, because poets and writers endow loneliness with blue. Loneliness is inner loneliness. Even if you look at the red color in the New Year, you are lonely. True loneliness is colorless, that is, nothingness. Lonely blue is just people idle and feel sad.
