The additive system is used most often in theatrical lighting (theatre plays, music concerts, circus shows, night clubs, etc.). A red spotlight and a blue spotlight are aimed at a performer on a stage, and where the spotlights overlap a magenta color is produced. This is additive color mixing. The red light is adding its wavelengths to the blue light, and a third color, magenta, is the result.
