There is no doubt that colors influence in an important way our state of mind and vice versa: any times we show our state of mind through the color we use to dress, make up, dye our hair, decorate our home, etc. It is not a coincidence that in autumn and winter we have more dark colors in our wardrobe, quite the reverse from what happens in spring and summer.
The importance of color in our lives is shown in the language throughout numerous idioms and colloquial expressions, using different colors.
