work of art featuring analogous colors

Quick answer：

Analogous colors are those that are next to each other on the color wheel. They create a harmonious and balanced look when used together in art. In a work of art featuring analogous colors, the artist typically selects colors that are close in hue, such as blue and blue-green or red and orange, to evoke a sense of unity and tranquility. This color scheme is often used in nature-inspired art or to convey a peaceful mood.
