The expression 'The Colors of the Four Seasons' refers to the various hues and shades that nature exhibits throughout the year, with each season having its distinct color palette. Spring is often associated with greenery and blooming flowers, summer with vibrant greens and warm colors, autumn with golden and red foliage, and winter with white snow and cold tones. This concept is often used in literature, art, and design to evoke the mood and atmosphere of each season.
