because when you look at a black object, little light reflects back to your eyes

When light of all colors (wavelengths) is absorbed by an object, the object appears black.
Black
An object that appears black is absorbing all colors therefore none of the colors in the spectrum are being reflected.
An object appears black because it absorbs all the colors of the visible spectrum. If we idealize the object to make it perfectly absorptive, it absorbs all of the white light that strikes it and reflects none. In the real world, some light is always reflected. If the object appears black or dark gray, then it reflects small amounts of all colors of the spectrum.
Blue what ? ! ? Do you mean an object that appears blue in white light ? Such an object appears black in green light.
When all light that hits an object is absorbed by it the object appears black. Similarly we see a wight object when all light that hits the object gets reflected off it!!!!!
it appears black
Black
I would assume it would be because of iridescence of the object. Some things, such as crow feathers, can appear to be bluish or greenish, either because of light or the physical properties of the object.
In red light a blue object appears black because there is no blue light for it to reflect, while black resembles the absence of all color.
The object appears black when no colors are reflected. (In actuality, some light is reflected by all objects, making black simply a very dark gray.)
A green object appears black when viewed through a red filter (here a red filter means red light) because green object can only reflect green color and absorb all the other colors so in the red light it will definitely appear black.
