Colour Depth

Color depth, also known as bit depth, refers to the amount of information stored for each pixel in an image, representing how many colors can be displayed. It is measured in bits: a higher bit depth allows for a greater range of colors. For example, an 8-bit color depth can show 256 colors, while a 24-bit depth can display over 16 million colors. This affects the image quality, with higher color depths resulting in more accurate and vibrant representations. In essence, color depth is crucial for producing realistic images in digital media.
