Abstract
A color input device includes a stylus, a color input unit installed in the stylus. The color input unit includes a circuit board, an MCU, a color sensor, a color display device, a Bluetooth module, a memory, a control interface and a power supply device respectively connected to the MCU. Through the control interface, the color sensor can be activated to capture nature colors and to store intake colors in the memory, and the colors stored in the memory can be displayed on the full color LED display and selected and transmitted to a computing device via the Bluetooth module, enabling the APP of the computing device to temporarily store the inputted colors and synchronously display them on the display device of the computing device. Furthermore, the color input device can receive colors or patterns from the computing device for establishing a diversified color database.
