This is an online color reference website that contains 17 sets of color schemes. Each set contains five colors and a background color combination. Clicking on a color scheme will show you its application effect on the website. The color code of each color element used will be labeled and can be copied by clicking on the color. In addition to color schemes, the website also shares some explanations of color terms, such as hue, saturation, brightness, chroma, and common scenes and uses for each color. For example, red is a very emotional and visually strong color that can affect the body's metabolism, breathing, heart rate and make people feel hungry. Red is also very eye-catching, so it is often used by fast food chains. This website is a good resource for novice designers.
