What does the RGB color model represent?

The RGB color model represents colors through the additive mixing of three primary colors: red, green, and blue. In this model, colors are created by combining these three basic colors in various intensities. When all three colors are mixed together at their full intensity, they produce white light, while the absence of all three results in black. This model is widely used in electronic displays and lighting applications because it aligns with the way human vision perceives color, making it a fundamental concept in both digital art and design.

The other options do not accurately represent the RGB model; for instance, the second choice incorrectly suggests it only utilizes red and blue, omitting green entirely. The third option implies that green is excluded, which is contrary to the model's definition. Lastly, the fourth option incorrectly associates RGB with color temperature, while RGB focuses on color mixing rather than temperature-based representation.
