What color is perceived when bright red, blue, and green light are mixed together?

When bright red, blue, and green light are mixed together, the result is perceived as white light. This occurs due to the additive color mixing process, where combining the primary colors of light—red, green, and blue (RGB)—in equal intensities produces white.

In additive color mixing, red and green light combine to create yellow, and blue and green light combine to form cyan. However, adding all three colors together at full brightness yields white, as they effectively stimulate all three types of color receptors in the human eye. Mixing lights in this manner contrasts with pigment mixing, where combining colors can lead to darker, more muted hues. This understanding of additive color mixing is essential in various applications, including digital displays and lighting design, where precise color reproduction is vital.
