The multiplication of two RGB Images is a pointwise operation. Each pixel element of the RGB image is multiplied by the correspondent pixel coordinate/element of the other image. It is possible to get very unexpected results.
In this experiment, we are multiplying an RGB image by constant color planes.
Shown below is the original RGB image.
