The Color Mixer is used to demonstrate how the eye combines color surfaces. This basic Color Mixer was specifically designed for classroom use. The color wheel spins the included color paper disks at speeds ranging from 200 to 2350 RPM. The 5-inch wheel includes degree marks so that varied proportions of color can be spun for different effects. The drive motor operates smoothly and quietly. The color disk replacement set - model AA86828-1- includes 19 precut -114 mm colored paper disks.

Colors are formed either by reflection (subtractive colors), using chromatic dye mixes, or by white light diffraction (additive colors), using filters or prisms. This system demonstrates the subtractive color formation using calibrated color disks. Disks are placed in a rotary disk plate for accurate RPM and color disk percentage selection. The system provides a way for accurately make chromatic mixes and rotate them at different RPM's to observe: color change, the effects of mixing different disks arrays and, introducing different variables to observe their effects in color perception.
Rotational speed can be easily fixed by using a smooth cue-less paddle control. Experimenters may choose to allow subjects to control the device, or to set the system at a desired speed. Start, Stop and Speed functions can be set by using stimulus software as e-prime from PST, and Observer from Noldus, among others used for experimental synchronization.

Experimenters or subjects can set the different color disks arrays and measure their relative percentage. Subjects place the disk array into the disk plate and secure it by using a thumb screw. The microprocessor-controlled motor is be set by using the LCD control or paddle. Subjective perception on color mix -disk array percentages- and RPM can be recorded in the provided recording format.
