It's like this - you are in front of your canvas, you hand holds the paint, ready, raised. The canvas waits, waits, empty and white - but all the time it knows what it wants. So - what does it want, anyway? My hand comes near, my eyes begin to transform the waiting canvas; and when - with my hands holding the paint and my eyes seeing the forms - I touch the canvas, it trembles, it comes to life.

'Karel Appel, excerpt', c. 1953
