Abstract - CMY mixer is used to mix colors of cyan,
magneta, yellow to produce different colors used for printing over a plastics.This project reduces time taken for mixing manually and produces accurate color blendings.The conventional method uses person in work to mix all three colors in assumption to produce desired blend of a color.It takes lot of time to mix all three colors since it uses error and trial method there will be some wastage. Naturally, there are two basic color models: RGB model and CMY model. RGB color model seems very logical from the first sight. It is upon this black surroundings that the little networks of lights in the screen display their various hues, essentially addition of coloration to the black of the background in order to make up the final target value. But CMY is considered subtractive because it calculates its correct hues by subtracting from the initial brightness of the paper in order to make up the final target value. For this very reason, CMY uses lighter secondary colors than those used by RGB coloration modes.Thus we go for the CMY model.References have discussed the detailed definition and introduction about CMY model. And, in this project, we just focus on the CMY mixer model.
2)Additive Color (projected light or reflected light): When all colors are mixed, the additive result is white.Colors are resulted from the projection of light.

1.2CMY COLOR MODEL CMY form the most basic and well-known color model. This model bears closest resemblance to how we perceive color. It also corresponds to the principles of additive and subtractive colors. 1.2.1CMY Cyan, magenta, and yellow are primary colors .In the illustration below, we can see the CMY counterpart to the RGB model shown in figure 1:

1.INTRODUCTION 1.1 BASICS OF COLOR THEORY Two Kinds of Color Process 1)Subtractive Color (reflected pigment):When all colors are mixed, the subtractive result is black. Substractive color is obtained from the absorption of light.

2.BLOCK DIAGRAM In this block diagram shown in figure 3, we explained about the project’s overview. Here input is given through a pc via usb cable of the microcontroller then microcontroller decrypts the input selection and operate the relays according to the input given.Colors of C,M,Y are pumped to the mixer vault.in order to obtain the perfect blend of output color we need perfect control of amount of
