Color film consists of three layers of what?

1. Film base

2. Emulsion

3. Plastic

4. Glass

The correct answer is: Emulsion

Color film consists of three layers of emulsion that are coated onto a film base. Each of these emulsion layers is sensitive to a different primary color of light: red, green, and blue. When exposed to light, each layer reacts to the colors in the image, allowing the film to capture a full spectrum of color. The layers work together during the development process to create the final image with accurate color representation. This characteristic is fundamental to how color film functions in capturing images, enabling photographers to produce photographs that closely resemble real-life colors. The film base provides structural support but does not contribute to the light-sensitive qualities that allow for color capture. Options such as plastic and glass do not accurately describe the composition related to how color images are formed with film, as they do not play a role in capturing or developing color in the same way emulsion does.
