I've seen her in person and I think she's "pretty" close to the movie colors (:wink: ). Keep also in mind how people were surprised by Bib Fortuna blue details when Attakus matched the colors of the actual clothes.
But it would definitly be interesting to see what reference pics Attakus has worked with. Because colors vary a lot depending on the pics (clothing tests, original shooting, special edition and not mentionning the different lightings).
Yellowish flesh tone
Green tone (body), more yellow for the head "tentacles"
Light green tone.
"Darker" green tone
