Which colors are considered additive colors?

1. Red, yellow, and blue

2. Red, green, and blue

3. Magenta, cyan, and yellow

4. Black, white, and gray

The correct answer is: Red, green, and blue

The assertion that red, green, and blue are additive colors is accurate because these colors correspond to the primary colors of light in the additive color model. When combined in various ways, these colors can create the full spectrum of visible light. When all three colors of light are present at full intensity, they combine to produce white light. This concept is foundational in contexts like digital screens and stage lighting where light is combined to produce various colors. Understanding additive color mixing is essential in interior design as it influences how colors appear in different lighting situations, affecting the perception of space and ambiance. Other combinations, like magenta, cyan, and yellow, pertain to subtractive color mixing used in processes like printing, where colors are created by absorbing and reflecting certain wavelengths from light.
