"The fact is that at different times you see with different eyes. You see differently in the morning from in the evening. The way in which one sees also depends on one's mood... If, in the morning, you come from a dark bedroom into the living room, then you might see everything in a blue light. Even the deepest shadows have a light atmosphere above them. After a while you get used to the light and the shadows get deeper and you see more sharply. If you are to paint such an atmosphere ... you cannot merely sit and stare at everything and paint it 'as accurately as you see it'. You must paint it as it appeared when the motif seized you. "
