I am confused which colors of the 36 skin tones set, are actually in the 120 color set. Looking at both sheets of colors, there are contradiction. A color on the skin tones may have a mark saying it is not in the 120 color set, yet it appears in the colors of the 120 set. Anyone know exactly what colors the skin tones set has compared to the 120 set?
