The new volume by Boerboom/Proetel is the highlight of the successful book series. Through numerous drawings and images, the authors make the use of color intuitively accessible. Material and effect: All aspects of color are illuminated. Colors are striking, sensual, and memorable. They adorn, soothe, touch, or confuse. Sometimes they overwhelm us, and we become intoxicated by them. This collection of experiments and exercises invites both beginners and professionals to explore the possibilities of color use in images. The dual nature of color plays an important role: on one hand, color is a painting material, a substance made of pigment and binder, and thus can be watery, pasty, or powdery. On the other hand, color is an immaterial phenomenon, has an effect, and can be bright, colorful, soft, or muted. Its true power unfolds between these two poles.
