A color space is a specific organization of colors that helps in the representation and reproduction of color in various devices, such as monitors, printers, and cameras. It defines a range of colors that can be displayed or captured, allowing for consistent color communication across different media. Common color spaces include RGB, CMYK, and HSV. Each color space uses a different method to represent colors. For example, RGB combines red, green, and blue light to create colors, while CMYK uses cyan, magenta, yellow, and black inks. Understanding color spaces is essential for graphic design, photography, and digital media.
