In photography, what does RGB stand for?

1. Red, Green, Blue

2. Red, Gray, Blue

3. Reddish, Greenish, Bluish

4. Reflective, Gradient, Blending

The correct answer is: Red, Green, Blue

RGB stands for Red, Green, Blue, which are the primary colors of light used in digital imaging and display technologies. This color model is based on the additive color theory, where various intensities of these three colors of light can be combined to create a wide spectrum of colors. In the context of photography and digital imaging, when red, green, and blue light are mixed together in different proportions, they can produce other colors. For example, combining red and green light yields yellow, green and blue produce cyan, and red and blue create magenta. When all three colors are combined at full intensity, the result is white light. Understanding the RGB color model is essential for photographers, especially when working with digital cameras, computer monitors, and editing software, as it plays a crucial role in how images are captured, displayed, and manipulated.
