Thermodynamics/blending colors

Question
Is White a colour? I've heard black isn't a colour but white is blending of all colours and is a colour

Answer
You can certainly go into a paint store and buy white paint or black paint.  If you blend all the wavelengths of visible light together, you get "white".  If you blend a lot of paints together you won't get white.  Black is sometimes defined as the absence of colour.
