Additive or Subtractive...
*
...two different ways to mix colors.
*
Additive colors are when you blend light.* White light is the presence of all colors, where black is the absence of any color light, or any light at all.* This is what is happening with a prism where you can break apart light into its varoius components.* Consider having three spotlights, one each color, red, green and blue.* You setup these lights so you can shine them on a white piece of paper.* Turn on the*blue light and you have a*blue spot of light, turn on the other two lights and the light will mix and you have a white spot!* Yup, this works, been there and done that.
*
Additive colors*are also how the monitor you are looking at right now works.* If you have a magnifying glass you can look at the white areas around these characters and see that it is really a set of red, green and blue pixels.* If you want a red spot on the screen the red pixel is turned on.* If you want a white spot you turn on*all three pixels in the set and the viewer sees a white spot.* Any other color can be made by mixing different brightnesses of the three pixels.*
*
Subtractive colors are when a material absorbs colors.* This is how pigments like crayons, inks and paints work.* A red pigment is a material that absorbs all colors but red, The red light is reflected and the viewer sees red.**likewise*a blue pigment is a material that absorbs all colors except blue.* When you mix pigments you get a material that absorbs more colors and will appear darker than the pigments you mixed.* Put enough of the right pigments into something and it will appear to be black as it absorbs all colors.* Thus a pigment subtracts colors from the reflected light.
*
Remember addition and subtraction works with colors
