Color-Grade 
Color-Grade mode uses color in the displayed waveform to show which values are most frequent 
in the waveform sample. Normally, display intensity is varied to give you hints about the most-
frequent values. Color-Grade  mode instead uses color to represent the relative  frequency of 
voltage or current values appearing in the waveform (it is similar to a histogram). 
Colors near red have the highest relative frequency and colors near blue have the lowest. For 
signals with random noise, Color-Grade mode is useful in helping you qualitatively understand 
the stochastic nature of the signal being measured. 
The  intermediate  colors  are  ordered  similarly  to  the  spectrum  of  white  light:
