Subtractive mixing occurs when

  • A.coloured lights are flashed in rapid succession
  • B.colourants each remove part of the spectrum from the light
  • C.lights of different wavelengths arrive at the eye together
  • D.small coloured dots are viewed from a great distance

Answer: B

Each colourant absorbs certain wavelengths, so what remains is progressively reduced. The result is always darker than either colourant taken alone. Each colourant removes part of what remains. The result is darker than either component.
