" I keep hoping that I’ll come up with something. To express the love of two lovers by the marriage of two complementary colours, their blending and their contrast, the mysterious vibrations of related tones. To express that thought of a brow by the radiance of a light tone against a dark background. To express hope by some star. Someone’s passion by the radiance of the setting sun. "
