The RGB Color Addition Interactive provides the user with an interactive light box for investigating the principles of color addition. Learners can quickly see the result of mixing red, green, and blue light in equal and unequal intensities. Once they learn the basics of color addition and the manner in which the mixing of light produces specific colors in an image, they can begin to experiment with the RGB characteristics of a screen image. Learners can investigate the provided image and even explore an image uploaded from their own device.

Launch Interactive

For now, users are encouraged to open the Interactive and explore. Or if desired, The Physics Classroom has prepared an activity for a more directed experience. The activity was designed with the intent of being used by classroom teachers with their classes. View Exercise.

Our RGB Color Addition simulation is now available with a Concept Checker. Do the simulation. Then follow it up with the Concept Checker.
