This model allows the student to perform his own colour synthesis from 3 miniature RGB LEDs. Three rotary knobs allow you to independently adjust the intensity of each of the 3 primary colours and thus compose the secondary colours and the white light.
A translucent sliding cover allows you to directly observe the 3 sources of primary colours or to observe the resulting synthesis through a small diffusing screen.
