Abstract

A color detection system includes a motherboard, a detection device, and a detection card. The detection device comprises a display unit and a memory unit storing a first color frequency setting value. The display unit displays a first color according to the color frequency setting value. The detection card includes a color sensor, a microcontroller, and a first connector. The color sensor generates a first color frequency current value after sensing the first color from the display unit and sends the first color frequency current value to the microcontroller. The microcontroller sends the first color frequency current value to the motherboard And the motherboard outputs detection success information to the display unit when a first difference value between the first color frequency current value and the first color frequency setting value is less than a predetermined value. The display unit displays the detection success information.
