Digital BW, The Print

Try some lasers half way inbetween the wavelengths of the RGB sensor. 
Works fine with B&W but not so well if RGB (if the filters are any good).

Of course nature is for the most part is close to white light but you 
can get three sources to look white while not white, it fools our eyes 
into thinking it is. But when shown on a color not one in the mixture 
the object will not reflect any light so look black. At best RGB is 
converted to the intensity at a wavelenght other than, red, green or 
blue at best an estimation and at times a poor one.
