Color is a tool to convey message and meaning. In this laboratory, we study how to use color to serve and support both personal and public needs. We do research which can be the evidences to drive the government policy of healthcare and safety. For example, we investigated the unattractive colors and applied the most unattractive colors on cigarette packaging. The result was an evidence which Thai government use to drive the plain cigarette packaging policy in 2019.We also study on the representative color or image color of product. These colors will be applied in product design, packaging design or other applications in order to improve the user experiences.
