|Additive Color Mixing|
This applet allows the user to paint on a canvas that mixes colors additively. Various parameters can be manipulated and some preset images can be loaded and also painted on.
|Combined Color Mixing|
This applet helps the user combine concepts in additive and subtractive color mixing through a scenario that includes lights, paints and filters. Users can directly observe how various colored lights, paints, and filters contribute additively as well as subtractively to produce a single color to be viewed by the applet's virtual eye.
This applet lets users experiment with metamers: different spectral distributions that are perceived as identical colors.
This applet explains the interaction between a surface's reflectance function and the spectral distribution of light illuminating it.
Given a spectral distribution and material reflectance, this applet shows how the RGB values of the product spectrum can differ depending on how these are calculated.
|Single Cell Response|
Given a frequency response curve, this applet examines the frequency response and total response generated from an arbitrary, user-specified input signal.
|Triple Cell Response|
Given three different response curves, this applet examines the resulting frequency responses and total responses given an arbitrary, user-specified input signal.
This applet examines what happens when two different surfaces are illuminated by a single light.
