When red, green, and blue colors of light are mixed in equal proportions, the resulting color will be white (Option B). This phenomenon is based on the additive color mixing principle, where different intensities of red, green, and blue light combine to create a broad spectrum of colors. When all three primary colors are mixed at full intensity, they stimulate the three types of color receptors (cones) in the human eye simultaneously, resulting in the perception of white light. This additive mixing is fundamental in technologies such as RGB color displays, where varying combinations of red, green, and blue pixels create millions of different colors and shades. Understanding additive color mixing helps in designing accurate color reproduction systems for digital imaging, visual displays, and other applications where precise color rendering is essential for conveying information and creating visual impact.
