Colors live a remarkable life of their own after they have been applied to the canvas.

If what you want to paint is the emotive mood in all its strength... then you must not sit and stare at everything and depict it exactly as one sees it.

I was walking along a road one evening – on one side lay the city, and below me was the fjord. The sun went down – the clouds were stained red, as if with blood. I felt as though the whole of nature was screaming – it seemed as though I could hear a scream. I painted that picture, painting the clouds like real blood. The colours screamed.

I was walking down the road with two friends when the sun set; suddenly, the sky turned as red as blood. I stopped and leaned against the fence, feeling unspeakably tired. Tongues of fire and blood stretched over the bluish black fjord. My friends went on walking, while I lagged behind, shivering with fear. Then I heard the enormous infinite scream of nature.

It is better to have a good painting with ten holes than ten bad paintings without any holes.

It would be quite amusing to preach a bit to all those people who for many years now have been looking at our paintings and either laughed or shook their heads reproachfully. They do not believe that these impressions, these instant sensations, could contain even the smallest grain of sanity. If a tree is red or blue, or a face is blue or green, they are sure that is insanity.

For as long as I can remember I have suffered from a deep feeling of anxiety which I have tried to express in my art.
