Have you ever noticed that red and yellow are often. used for warning signs? Vivid and warm colors are chosen because they catch people's attention.

For example, emergency exit signs show a picture of a green figure on a white background. The contrast between green and white parts helps us distinguish the figure clearly from its background even in smoke or fire.
