Colour theory in lighting in Lighting Posted October 6 Hello all, I've got a lighting challenge that I'm unsure about. I'm shooting a commercial on a small studio set with a solid blue backdrop and one 'character'. For the opening I want to have a spot on the backdrop which silhouettes the character, before the spot gets killed and the main lighting for the rest of the ad faded up. My question is - in an attempt to get a solid white spotlight on a primary blue backdrop is it as simple as picking a 'complimentary' colour for the spotlight, e.g. yellow/red? Trying to apply some basic colour theory stuff which I've been reading up on but not put into practice too much yet. I'm unsure about the ability to achieve this effect in post as the character is also being lit by a dim blue light from a laptop/tablet whilst the white spot silhouettes them. Cheers!
