Answer: 1.) subtractive mixture of colours above a white surface 2.) additive mixture of light of different colour on a black background You can easily see the difference on your computer screen, if you use a strong magnifying lens. Then you would see tiny dots in red, blue and green, which together create the impression of white. If you subtract the colours, you use the opposite colours called yellow, magenta and cyan, (which is roughly yellow red and blue). ... > > If you buy a jar of White paint, (Red, Blue and Green mixed) and you add Blue...you get White. Definitely not !!! If you mix white and blue paint you get light blue. TH
