The precise mixing of paint colors is crucial in painting industry. This process requires high accuracy and skill in measuring the base colors needed to produce the desired final color. But in most case paint mixing process still be done in a manual way which can pose risks, such as generating inconsistent or inaccurate colors. Based on these conditions this research aims to design paint mixing device to assist in achieving more accurate and efficient color mixing process by using Arduino as the main processor to control paint measurements through integration with TCS-3200 sensors and actuators to improve efficiency and the quality of color mixing based on specific requirements. Result of the tests showed that the device able to perform a promising result, with the average error value of just 9,61%. Several factor which may affect of the results include light ambience condition around the device, paint color calibration, and uniformity in of the paint color used.
