I made a reference sheet for myself; I might end up updating this in the future though, but this should work for now.

Here are the hexadecimal values for the colors listed in the corner (left to right):
#25a5a1 #26d5da #c9a4cb #c0e1e1 #c1ce87 #875538 #31241c #2f677e #6f4132

The clothes can basically be any color, except for the shoes; they must be dark-purple with light-colored soles.
