And pink. Not really blue though.

She has prepared the green gown for the coronation which must be very special to her. And in the ending, she wears green too. Meanwhile, the blue dress is the only one left in Oaken's so she has no choice but buys it. Besides, because she wears the pink coat, we can see her more of pink than blue.

After watching Frozen, I asked myself this question, oddly enough. I immediately thought GREEN. For the reasons LightningRed said above. ^

I think that pink fits her because it resembles energy (because Anna is pretty much an energetic person), fearlessness and it also attracts attention, much like Anna. Also she wears Pink almost all throughout the movie.

I don't know because i love colors but i thinks about green is Anna's principal color.

I think green is her color because in the song For the First Time in Forever, as a little girl, a preteen and a teen she wears a green dress. And she wears green for the coronation and at the end of the movie. So it is 1 pink dress we see mostly and 5 green dresses. It makes sense.

I am going go with green because it is the color she wears the most. I do like the blue dress and the pink cape she wore too.

I think all of her outfits in her wardrobe are all green. Look! From her childhood outfits, nightdress, coronation gown, and her common outfit which is in the end of the movie are all green! Her blue dress and pink coat is from Oaken.

The green outfit that she wore at the end of the movie looked great on her! The pink dress looked good, but the blue dress didn't fit her character. The blue dress made her look calm and mature, which obviously, doesn't represent Anna.

I think it fits her hair color better plus she looks amazing in green clothes like at that ball where her sister gets crowned. Anna looks fabulous in green ;)

shes lively like green color

I think her favorite color is green because she wears green a lot :D

Green is my favorite color. It's all natural and stuff. I like the other colors, too, though. <3

Also, green matches her hair best I believe.
