Our eyes interpret black as basically an area devoid of colour. We can also scientifically measure how we perceive colour in general. Basically each colour is just microscopic variations in wavelengths of light.
Black doesn't and can not be defined as a colour as it is not part of the visible light section of the electromagnetic spectrum.

Yea that's what I was trying to get at, nice one
My thinking is that by calling black an absence of light, when light is shone on a black object then it should be invisible/non existant because light would be present - not absent.
Therefore I believe black to be a colour as we can see it when light is present, and as mentioned by Neo, light is not required for a colour to exist.
Colour is ultimately our minds interpretation of differentiating the different forms of light that reaching our eyes. Obviously the light produced depends upon the properties of the object it hits, so when you turn the light off the object obviously doesn't change. This merely means that the object retains the properties needed to reflect red light when light is present but it is no longer red as objects have no predetermined colour. Colour is only in our mind and without light can't really exist.
It cannot exist as energy without light. It still exists at the elemental level. The definition of color only changes when looking at the different mediums in which it can exist. Color's definition is not ambiguous.
Apparently black is not a color.
I do not know how to respond to that. It does make sense.
I mean a "black" ink-pen's ink is not really black but extremely dark blue or purple in most cases. So as I said I do not know.
But Neo makes a well thought out point and so does Potatoe Chip
