1. When it's absorbed into a medium, it will affect how things look. It limits the light available to be reflected or transmitted.
2. There's a thing that is called a light filter that is transparent to some kinds of light but is opaque to others. Sunglasses use these material to block out sunlight.
3. A black T-shirt will be a black T-shirt after it is painted, by any colors.
