Color contrast refers to the difference in color that makes objects stand out from one another. When two colors are placed next to each other, a strong contrast can make one color appear more vibrant or noticeable. For example, a bright yellow text on a blue background is easy to read because the colors are very different from each other. In design, using color contrast effectively can enhance visual appeal and improve readability. High contrast can draw attention to important elements, like a call-to-action button on a website. Conversely, low contrast can create a softer look, but may make text harder to read, especially for those with visual impairments.
