This first website isa good source that displays many of the ways light produces color. It explains the different ways that color works through color filters. It provides the combinations and spectrums to produce certain color effects. Good source to further see more examples of how filters absorb and block colors in light.
Smithsonian Library: https://library.si.edu/exhibition/color-in-a-new-light/science
This website provides many historic revelations to color theories and how humans perceive color. Provides information about Isa Newton and other people who studied color theories. Color blindness is another thing that we did not discuss and is very interesting to look into.
Color Blindness: http://www.colourblindawareness.org/colour-blindness/causes-of-colour-blindness/
This website explains why a color blind person is unable to see certain colors due to the human cones and rods that are unable to register colors. One type of cone perceives blue light, another perceives green and the third perceives red. When you look at an object, light enters your eye and stimulates the cone cells. Your brain then interprets the signals from the cones cells so that you can see the colour of the object. The red, green and blue cones all work together allowing you to see the whole spectrum of colours. For example, when the red and blue cones are simulated in a certain way you will see the colour purple.
Learning Hub: https://www.sciencelearn.org.nz/resources/47-colours-of-light
This website includes more information about the wavelengths that light and specifically the color spectrum work within. It too discuss how we view everyday objects colors such as shirts and pants. It also explains the difference between additive and subtractive color.
