The host counters this by explaining how RGB light works. When red, green, and blue light combine at maximum intensity, they indeed produce white light — a principle widely used in displays. The white color on screens results from overlaying different intensities of RGB LEDs, which the host illustrates with a controllable RGB LED panel. By adjusting each color’s brightness, they produce various colors, including white, which is simply created by setting all three channels to full intensity.
