Do I sound obsessed?

And here is some more about Mondrian - maybe I am obsessed!
This is still from the Harvard site - a mine of information:
"Mondrian's favorite yellow pigment was cadmium yellow. The British painter Winifred Nicholson remembered the following exchange:

"You are the first person who has ever painted Yellow," I said to him once, "pure lemon yellow like the sun." He denied it, but next time I saw him, he took up the remark. "I have thought about it," he said, "and it is so, but it is merely because Cadmium yellow pigment has been invented.""
