The term "255" in color refers to the maximum value in the RGB color model, which stands for Red, Green, and Blue. In this model, colors are created by combining these three primary colors in varying intensities, each ranging from 0 to 255. When all three colors are set to 255, the result is pure white, while 0 for all three results in black. In digital design and programming, the value 255 is often used to represent the brightest intensity of a color. For example, the color RGB(255, 0, 0) represents bright red, while RGB(0, 255, 0) represents bright green. Understanding these values is essential for graphic design, web development, and digital art.
