There is silver blue, sky blue and thunder blue. Every color holds within it a soul, which makes me happy or repels me, and which acts as a stimulus.… - Emil Nolde

None of the free [ a.o. his first religious] imaginative pictures that I painted at this time [c.1909] or later, had any kind of model, or even a clearly conceived idea. It was quite easy for me to imagine a work right down to its smallest details, and in fact my preconceptions were usually far more beautiful than the painted outcome: I became the copyist of the idea. Therefore I liked to avoid thinking about a picture beforehand, all I needed was a vague idea of luminescences of colour. The work then developed of its own accord under my hands.

I want so much for my work to grow forth out of the material, just as in nature the plants grow forth out of the earth, which corresponds to their character. In the print 'Lebensfreude' [Joy of living] I worked for the most part with my finger, and the effect I hoped for was achieved. There is hidden in the print a bit of wantonness, in the representation as well as in the boldness of the technique. If I were to make the "ragged and moving" contours "correctly" in the academic sense, this effect would not nearly be achieved.

I produce a form, an impression of light, a beauty of tones.. .The etchings are now full of life, an ecstasy, a dance, a gentle motion and fluctuation in tones.
