Transparent objects are those that allow large quantities of light to pass through; air, water and shiny glass are all examples of transparent materials. Transparent objects vary in the amount or types of light that they let through their surfaces. Glass is transparent for all visible lights; it reflects all colors of the rainbow, while other objects absorb certain colors and reflect others.
The color adopted by transparent objects depends on the color of light they transmit. When green light passes through transparent objects, green light is reflected back, making the object appear that color. Some objects appear as single colors, while others have more complex color patterns.
