Yellow can express happiness, and then again, pain. There is flame red, blood red, and rose red; there is silver blue, sky blue, and thunder blue; every color harbors its own soul, delighting or disgusting or stimulating me.
Emil NoldeThe artist need not know very much, best of all let him work instinctively and paint as naturally as he breathes or walks.
Emil NoldeThere is silver blue, sky blue and thunder blue. Every colour holds within it a soul, which makes me happy or repels me, and which acts as a stimulus. To a person who has no art in him, colours are colours, tones tones...and that is all. All their consequences for the human spirit, which range between heaven to hell, just go unnoticed.
Emil Nolde
