You're 100% correct, but I think she borrowed the colors directly from the pictures of Jennifer Lawrence from the EW shoot, which would explain why she was so light skinned.
Which is not a good thing, since Katniss as a character was whitewashed due to the casting of Jennifer Lawrence. As much as I love Jenny L., I don't think she quite suits the way the character was supposed to look. By the way, daekazu got the skin color spot on in some other pictures that she did..
