Light Interaction and Color Theory

The video tutorial introduces the indoor environmental control course, covering topics such as lighting, noise reduction, and thermal comfort. It delves into the physics of light, color theory, and models, including the Munsell system and CIE chromaticity chart. The tutorial explains light transmission, measurement units like candela and lux, and the inverse square law. It concludes with a discussion on surface properties and a copyright notice.
