The word "albedo" is used to describe the proportion of incoming light that is reflected. So an object with an albedo of .7 reflects 70% of the light that impacts it, while an object with an albedo of .02 reflects only 2% of the light, absorbing the other 98%.
ANY material reflects light. Some do so better than others.
A material that reflects or absorbs any light that strikes it is opaque.Tranlucent or transparent materials allow some or all light to pass through.

No material reflects all light. Silver is pretty close, which is why it is used for mirrors. As far as absorbing, porous black materials do the best job.

The material's Luster (lustrous would mean it reflects light) (dull is the opposite)
-- A portion of the light energy reflects back from the surface of the material. -- A portion of thelight energy is absorbed into the material and never seen again. -- The remainder of the light energy proceeds on through the material and emerges unbowed and undeterred from the other side.
an opaque material that reflects light
The color of light a material reflects depends on its molecular structure. For example, grass reflects green light so it appears green while it absorbs the other colors.
