Which colour appears when blue and green light are combined on a digital screen?

Answer and explanation

Correct answer: Cyan

The governing concept is additive colour mixing, used by screens and the RGB model. Blue light and green light stimulate the eye together; their combined signal is perceived as cyan, so option A is correct. Yellow requires red plus green light. Orange and brown are not the standard results of combining equal blue and green screen light, and brown usually depends on lower brightness and surrounding colours.
