Original Description:
 
Made an overly detailed chart for data only I care about!~  
Basically I was wondering on the amount of humanizations and the trends of how people humanize them. (For example Izzy used to be drawn almost always pale, but now its more common to see a darker skinned izzy)  
I went thru the “g5, humanized” search and counted them myself (they arent perfect for that reason obv)  
The specific tones are broad ranges and not hyperspecific, I exaggerated the ones used for the sake of the chart clarity.
