What is produced when red, green and blue light are combined at equal intensity in the RGB model?

Answer and explanation

Correct answer: White light

RGB uses additive mixing: the light energy from red, green and blue combines rather than being absorbed by pigments. When all three channels are present at equal, sufficiently high intensity, their combined stimulation is perceived as white light. Black represents the absence of emitted light, while brown and orange require different combinations or lower intensities. Thus option B is correct.
