What do the letters RGB stand for in color representation?

The correct answer is rooted in the foundational principles of digital color representation. RGB stands for Red, Green, and Blue, which are the primary colors of light used in various electronic displays such as computer monitors, televisions, and cameras. In the RGB color model, colors are created by combining these three colors in different intensities. When combined at full intensity, they create white light, while the absence of all three colors results in black.

This model is essential for web development and digital imaging because it aligns with the way screens emit light. Each color intensity is typically represented by a value ranging from 0 to 255, allowing for a wide spectrum of colors to be represented through combinations of these three primary colors.

The other options reflect concepts that are unrelated to the RGB color model, as they refer to different contexts in technology—such as graphic formats or color processes that do not involve the direct mixing of light as RGB does. Understanding the RGB color model is crucial for web developers to create visually appealing designs that render correctly across various digital platforms.
