White - Magenta = R+G+B - R+B = G = green Yellow - Green = R+G - G = R = red (Note the similarity to part f.) Red + Green - Green = R + G - G = R = red White - Yellow = R+G+B - R+G = B = blueį. White - Blue - Green = R+G+B - B - G = R = redĮ. White - Green = R+G+B - G = R+B = magentaĭ. White - Blue = R+G+B - B = R+G = YellowĬ. Then 'do the arithmetic.' If the result of the 'arithmetic' is a combination of two primary colors, translate the combo into a secondary color of light.

Select colors from the Color Table at the right.Įach of these questions is best answered by first converting any secondary color of light into a mix of two primary colors of light. Demonstrate your understanding of color subtraction by completing the following color equations. The result of combining these three primary colors of light is to produce white light.ġ7. So combining blue with yellow light is like combining blue light with red and green light. Yellow light is a combination of red and green light. White light is formed when all three primary colors of light are combined in equal amounts.Į. Cyan is a secondary color of light formed by combining green light with blue light in equal amounts. Yellow is a secondary color of light formed by combining red light with green light in equal amounts. Magenta is a secondary color of light formed by combining red light with blue light in equal amounts. Select colors from the Color Table at the right.Ī. Demonstrate your understanding of color addition by completing the following color equations. To assist in recalling the three primary colors of light, three secondary colors of light, and the means by which adding primaries form secondaries, develop some form of graphical reminder such as a color wheel or a diagram like those at the right.ġ6. You must know this for it forms the foundation of much of our reasoning. Choose the three colors in respective order. Combining red and green light (with equal intensity) makes _ light combining red and blue light (with equal intensity) makes _ light and combining blue and green light (with equal intensity) makes _ light. And mixing red and green light results in yellow light.ġ5. Mixing red and blue light results in magenta light. Mixing blue and green light results in cyan light.

The secondary colors of light are those colors which are formed when two primary colors are mixed in equal amounts. nonsense! There are more than three secondary colors of light. The three secondary colors of light are _.Į. Yes, you must know this one! It forms the basis of most of our logic and reasoning about color, light and the appearance of objects.ġ4. nonsense! There are more than three primary colors of light. The three primary colors of light are _.Į. Objects appear white when they reflect or emit all wavelengths of visible light (or at least three wavelengths - Red, Blue and Green - in equal intensity).ġ3. White is the presence of all colors of visible light. Things appear black when they do not reflect or emit light. TRUE or FALSE: White and black are actual colors of light.īlack is the absence of all light.
