Yellow sits between yellow-orange and yellow-green in the color wheel. Being the most visible color from a distance, it is often used as a cautionary color.
The color of sunshine and sunflowers, yellow is optimistic, playful, and happy. It can also be associated with mental clarity and intellect.
Yellow comes in a variety of colors—from sunshine yellow to golden yellow—and works well with its complementary color, purple. Bright yellow can be used as a pop of color for highlight or accent.
