no technical, but aesthetic ..the tops example contains more colour.. if you use the color slider, everything makes one colour.. what makes the whole image unrealistic.
..and yes, definiatly have one color shirt, top, what is looking good with color changed, but not much.
so we decided we did not put colors for the tops (but the boots and pants have example), but later, if you want it, really, we cimplement it easy way, but i am not really want.
i hope i answered your question 😀 (tihs is why i am against the skin coloring.. example one skin, what you see “tan”, its 4-5 colors.. if you change it, it will be one colour.. not will be the same)
