non-luminous objects
An object that does not allow light to pass through it is called opaque. Opaque objects absorb or reflect light, preventing it from transmitting through them.
Those objects are called opaque objects. They prevent light from passing through them, creating shadows when they block light from a source.
For exactly the reason that you call it a "a green object". You describe it that way because most of the time, when it's being illuminated by light of all colors, the only color that it does NOT absorb, and that remains to bounce off of the object and be seen by your eye, is the green. When there is no green light striking the object, it can't reflect any light to your eye, and it appears black.
The appearance of an object created by the quality of light it absorbs or reflects is called its color. The color of an object is determined by the wavelengths of light that are reflected off its surface. Objects appear a certain color because they reflect that color of light and absorb other colors.
OPAQUE is the word that describes an object or substance that blocks light (or other energy form). TRANSLUCENT describes objects that allow transmission of light, but scatter it from the original form or direction. TRANSPARENT describes objects that allow the passage of light, usually optically clear substances such as glass.

If by "light" you mean electromagnetic radiation, then you would call them energy radiators.
Luminous objects are those that emit their own light, such as stars, the sun, and certain artificial light sources like lamps and LEDs. In contrast, non-luminous objects do not produce light but can reflect it, such as the moon or a painted wall. The term "luminous" comes from the Latin word "luminosus," meaning "full of light."

You could call it interstellar or interplanetary space, depending on the context of the objects involved.
An object without color is black. Black does not reflect any wavelengths of white light back to the viewer, so the viewer will not perceive a color. The best example of this is empty areas of outer space. i think you would call it opaque

You only "see" when light enters your eyes. In the dark, there is no light . . . the main reason why we call it "dark". Since there is no light, none can enter your eyes, and you do not see.

This answer is very scientific.You see, the only reason you see something is because light reflects off of it and into your eyes. Light in itself is what is call electromagnetic radiation.Light has what is called wavelength. this means that different wavelengths of light will have different properties. Simple right?Now, when light is in its basic form, it is all the wavelengths (colors) mixed together. However, when it hits some, a leaf for instance, some of those wavelengths (colors) are absorbed and some are reflected.When the light hits the leaf all the wavelengths (colors) but green are absorbed. The green light is reflected back into your eye, causing the leaf to appear green.--**Basicly**--all things absorb some colors and reflect some colors. leaves absorb everything but green light, and that green light is reflected back into your eye.Things that are white reflect all of the colors, while things that are black absorb all the colors.
