There are two ways to make a color, and they work in opposite directions. Drag things around and find out for yourself.
Three spotlights in the dark. Drag them on top of each other and watch what happens when they cross.
Now three blobs of wet paint on white paper. Same idea, and the exact opposite result.
Set the amounts yourself. Light adds up toward white. Paint takes away toward black.
Five rounds. Move the sliders until your color looks close to the one on the left, then lock it in. Nobody hits it exactly, that is not the game.
