coz as u said black n white are themselves colours, and so we say Black n White..

ah v sahe lagaWe call b&w tv by its two color name so as to diffentiate it from multi colored tv. Moreover b&w is much simple for a layman to understand than the original word "monochrome".

we have ,
Black = colour
white = colour
so black & white = colour & colour
black & white= 2 colours ( coz according to boolean algebra & is equal to + )
therefore , black & white is 2 colour
therefore black & white tv is not a colour tv
