Cytat: Today I am probably going to begin on the interior of the café where I have a room, by gas light, in the evening. It is what they call here a „café de nuit” (they are fairly frequent here), staying open all night. „Night prowlers” can take refuge there when they have no money to pay for a lodging, or are too drunk to be taken in.(ang.).

Cytat: I have tried to express the terrible passions of humanity by means of red and green. The room is blood red and dark yellow with a green billiard table in the middle; there are four lemon-yellow lamps with a glow of orange and green. Everywhere there is a clash and contrast of the most alien reds and greens, in the figures of little sleeping hooligans, in the empty dreary room, in violet and blue. The blood-red and the yellow-green of the billiard table, for instance, contrast with the soft tender Louis XV green of the counter, on which there is a rose nosegay. The white clothes of the landlord, watchful in a corner of that furnace, turn lemon-yellow, or pale luminous green. I am making a drawing of it with the tones in watercolour to send to you tomorrow, to give you some idea of it(ang.).

Cytat: In my picture of the „Night Café” I have tried to express the idea that the café is a place where one can ruin oneself, go mad or commit a crime. So I have tried to express, as it were, the powers of darkness in a low public house, by soft Louis XV green and malachite, contrasting with yellow-green and harsh blue-greens, and all this in an atmosphere like a devil's furnace, of pale sulphur(ang.).
