reflection
Opaque
No, everything that we can see (besides objects the produce light eg sun, light bulb) reflect light. If it didn't reflect light we would not be able to see it.
the substances that are called opaque reflect light by whch they gain colour
Dark objects do not reflect light. Light is absorbed by them.

Yes. There is hardly anything that reflects NO light; dark objects simply reflect less light than light objects.

You cannot see your reflection in all objects that reflect light because of diffuse reflection.

The phenomena of sending back of light is called reflection of light. And the surfaces which reflects light back are called reflecting surfaces.
Brown objects reflect som light in the yellowish/orangish part of the spectrum. "dirty" orange is called "brown".
non-luminous objects
All objects reflect the color of light that you see. Thus; lemons reflect yellow light rays, limes reflect green ones, and Oranges reflect orange light rays. On a final note, white objects reflect all colored light waves, and black objects reflect none. With that said, the cones in your retina register these reflected light rays; thus, it makes sense that rooms without any light are black.
