And I started with this: I have not painted at all my childhood. In fact, I never painted. But I helped my father who was a house painter and decorative painter. He made stage sets, he made glass paintings, he made everything.

Instead of art I have taught philosophy. Though technique for me is a big word, I never have taught how to paint. All my doing was to make people to see.

My father's parents were carpenters. They were also builders partly. They were painters. And several of them were very, active in the theatre and all such nonsense, you know.

Color deceives continuously.

As basic rules of a language must be practiced continually, and therefore are never fixed, so exercises toward distinct color effects never are done or over. New and different cases will be discovered time and again.

We never really perceive what color is physically!

Good teaching is more a giving of right questions than a giving of right answers.
