Final answer:
Monochromatic colors are variations of one color that are created by adding black, gray, or white. Warm and cool colors are divided into different ranges on the color wheel and can be paired together for interesting results. Analogous colors are colors that are next to each other on the color wheel and blend together smoothly.
Step-by-step explanation:
Monochromatic Colors:
Monochromatic colors refer to variations of one color, which are produced by adding black, gray, or white. This creates a color scheme that has a high level of unity because all the tones relate to one another. For example, in Monet's 'Untitled (Houses of Parliament, London)' from c. 1900, he used variations of blue to create a monochromatic color scheme.
Warm and Cool Colors:
The color wheel is divided into warm and cool colors. Warm colors range from yellow to red, while cool colors range from yellow-green to violet. Pairing warm and cool colors together can create complex and visually appealing results.
Analogous Colors:
Analogous colors are colors that are next to each other on the color wheel and tend to blend together smoothly. For example, red and orange or blue and green are analogous colors. These colors create a harmonious and cohesive color scheme.
