Shadow is a colour as light is, but less brilliant; light and shadow are only the relation of two tones.

Pure drawing is an abstraction. Drawing and colour are not distinct, everything in nature is coloured.

There are only twelve tones and they need to be treated carefully.

My nervous system is enfeebled, only work in oils can sustain me.

Tak ada satu hal pun tanpa bayang-bayang, kecuali terang itu sendiri.

Desire, desire which knows, we draw no advantage from our shadows except from some veritable sovereignties accompanied by invisible flames, invisible chains, which, coming to light, step after step, cause us to shine.
