It is not bright colors but good drawing that makes figures beautiful.
As quoted in The Quotable Artist (2002) by Peggy Hadden, p. 32
Not every painter has a gift for painting, in fact, many painters are disappointed when they meet with difficulties in art. Painting done under pressure by artists without the necessary talent can only give rise to formlessness, as painting is a profession that requires peace of mind. The painter must always seek the essence of things, always represent the essential characteristics and emotions of the person he is painting...Titian
He who improvises can never make a perfect line of poetry.Titian
