TynkaTopi - Very good to know - thank you!
Color by elevation is one thing I’ll play around with, but this current study is associated with vetting a piece of software and the user defined values that are getting plugged into its algorithm. If you’re not interested in the details, feel free to stop reading;)
MCC-LIDAR will look at the  Unclassified lidar points and re-classify them according to (2) user inputs; threshold and scale. s values are linked with point density where as threshold is still voodoo to me. The bottom line: new ground points emerge and when tweaked to the sweet spot, will render a more accurate bare-earth model. So for now, color schemes will be limited;  102,102,153 and for  153,204,153 (RGB).
I very much appreciate all of your help and all of the other helpful voices here on the forum.
