The saying "black is not a color" implies a certain meaning of the word "color" which has nothing to do with whether objects can appear black or not.
It basically comes down to a question of semantics, which has a lot more to do with language than it does with physics. Ultimately, "don't worry about it" is probably the best answer.
By definition, black is the absence of light and color. In the real world, all objects with the possible exception of black holes reflect some light, but objects that appear black are absorbing, rather than reflecting, most wavelengths (colors) of visible light.
The color of an object has to do with the waves of (visible) light that it reflects. When light hits an object some is absorbed and some reflects, e.g. white is white because all the colours are reflected back; black is black because none of the colours are reflected, red is red because only red reflects from the object. Plants are green because the chlorophyll reflects the colour green, making them appear green to us.

Brown objects reflect som light in the yellowish/orangish part of the spectrum. "dirty" orange is called "brown".
it depends on what kind of object is that

No, color can not be seen in the dark. The only color that can be seen in the dark is black, because it is dark. If it is not completely dark then you might be able to see the color of some objects.
Yes, if you're blind then your eye is either pale grey or a darker shade of grey, which you'd call black. I hope this helped! ANSWER: A true black iris color does not exist, but some people have such dark brown eyes that they appear to be black.
A tornado can appear black for a number of reasons. A tornado that is strongly backlit may appear black because it is blocking a lot of light. A tornado that is lifting up large quantities of soil takes on the soil color, and some soil is black
No. The fish in the deep sea vary in color. Some even have their own lights on their body.

An object that reflects green and red light would be some shade of yellow or orange, depending on the proportions.
black! or green! or whatever eye colors could be!
Tornadoes do not always appear black. The apparent color depends on lighting conditions and how much and what color of soil is being lifted. Many tornadoes appear dark because of perspective: the are lit from behind and are essentially silhouetted against the light source. The same tornado may appear lighter if viewed from a different angle. The storms that spawn tornadoes have very thick clouds that often making conditions appear very dark. The clouds themselves may be black. Some tornadoes may be black as they lift large amounts of black soil into the air.
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.)
Unless it comes out of a bottle, no, there isn't. There are just shades of brown from light to very dark which, against some skin tones and accentuated by eye color, can appear black.
Black. In some light conditions it may appear to be iridescent and show a varied display of petrol colours (blue, green, purple etc.)
