Ben, a physics teacher and Lucy, an art teacher were arguing about what color red mixed with blue makes. Ben said it made magenta but Lucy said it made purple. Who is correct?


Answer

They are both correct. The three primaries for color are red, blue and yellow. The three primaries for light are red, blue and green. When mixing colors, red + blue = purple, but when mixing light, red + blue = magenta.
