The primary color pigments and the ratios required for toning the respective colors are stored in the memory 640, and a color palette can be displayed on the touch control panel 650.

When the color palette is used, a certain color of the color palette on the touch control screen 650 is clicked, the microcontroller 630 calls primary color pigments and proportions required by the color from the memory 640, then the stepping motor 200 is driven to work through the stepping motor driver 300, and the support frame 400 is driven to drive the pigment supply mechanism to rotate, so that the required primary color pigment supply mechanism sequentially rotates to the upper part of the material receiving groove 120, and the required primary color pigments are sequentially added into the color mixing cup 130 placed in the material receiving groove 120 in proportion. For example, when pink needs to be called, the user clicks on the pink palette on the touch control panel 650, the microcontroller 630 retrieves the primary color pigment and the proportion (for example, red: white ═ 1: 1) needed for calling pink from the memory 640, the microcontroller 630 drives the stepping motor 200 to rotate 60 degrees from the initial position through the stepping motor driver 300, so that the red pigment supply mechanism 510 is located above the receiving slot 120, and then the microcontroller 630 controls the electromagnetic metering pump in the red pigment supply mechanism 510 to add 1 part of the red pigment into the toning cup 130 placed in the receiving slot 120; then the microcontroller 630 drives the stepping motor 200 to rotate 300 degrees from the initial position through the stepping motor driver 300, so that the white pigment supply mechanism 550 is located above the material receiving groove 120, then the microcontroller 630 controls an electromagnetic metering pump in the white pigment supply mechanism 550 to add 1 part of white pigment into the toning cup 130 placed in the material receiving groove 120, the toning cup 130 is taken out, and the red pigment and the white pigment in the toning cup are uniformly mixed by using a painting brush. The toning of the rest of the pigments is similar, so the description is omitted.
