. . . the kind of information shown in a television 
image is of a very low-grade, poor quality which the 
public has to complete and fill in for itself every 
instant by a considerable effort or participation. 
Color creates another lowering of definition and 
involves even more participation than black and 
white. It is more faithful to the nature of TV to be in 
color because color is itself one of those very tactile 
forms of participation.
