Saturation and Brightness

Objective: The students will make observations in regard to saturation
and brightness of colors while using the Java Gel Color Mixer. The
students will be able to identify those colors which are brighter and/or

note the change and repeat the procedure using the blue and red
faders.

Questions:

of red and green changes to what color?
