Synthesis and Analysis of Color – 6F10.00
Additive and Subtractive Primaries – 6F10.19
- A slit and its negative (a slat) is placed on the overhead.
- A diffraction grating is placed in front of the overhead lens, resulting in production of two spectra: One “normal” and the other containing colors such as magenta and cyan.

Hand-Crank Color Mixing Spinner – 6F10.25
- Chemiluminescent Light Addition is done by snapping the red, blue, and green light sticks and attaching them to the axle. Dim the lights, turn the crank, and observe a circle of white light.
- By wrapping black electrical tape on the blue light stick and spinning you can see a band of yellow at the edge of the circle.

Complementary Spectrum with Slit and Inverted Slit – 6F10.26
- A slit and “inverted slit” used with Hg and a prism produce the normal line spectra and “inverted spectrum” of complementary colors.

Tri-Color LED – 6F10.36
- Push each button in turn to show the 3 colors (RGB) that light up the Plexiglas triangle.
- Push each combination of 2 colors to see the resulting color (CMY).
- Push all 3 buttons at the same time to show the resulting white light from adding RGB.
