Final answer:
The Blind Man's Meal painting by Picasso is an example of a monochromatic color scheme.
Step-by-step explanation:
The correct answer is 1) Monochromatic. In Picasso's painting The Blind Man's Meal, a single color predominates the entire work. This is known as a monochromatic color scheme, where variations of a single hue are used. This creates a high level of unity throughout the artwork because all the tones relate to one another. An example of a monochromatic color scheme can be seen in Monet's Untitled (Houses of Parliament, London) from c. 1900.
