színmélységét

Színmélység refers to the number of bits used to represent the color of a single pixel in a digital image or display. A higher color depth allows for a wider range of colors to be displayed, resulting in more nuanced and realistic images. The most common color depths are 8-bit, 16-bit, 24-bit, and 30-bit.

In an 8-bit color system, each pixel can display 256 distinct colors. This was common in early computing but is now considered very limited. A 16-bit color system, also known as High Color, can represent 65,536 colors. This offers a significant improvement over 8-bit but can still exhibit banding in gradients.

The most widely used standard today is 24-bit color, often referred to as True Color. This system allocates 8 bits to each of the three primary color channels: red, green, and blue (RGB). This results in 256 levels of intensity for each channel, allowing for a total of 16,777,216 possible colors. This depth is sufficient for most visual applications and closely matches the range of colors the human eye can perceive.

Higher color depths, such as 30-bit (10 bits per channel for RGB) and 36-bit (12 bits per channel), are used in professional photography, graphic design, and high-end displays. These provide even smoother gradients and greater accuracy, crucial for tasks where subtle color variations are important. The higher the color depth, the more data is required to store and process an image, which impacts file sizes and processing power needs.
