Yellow, red, or blue

I've always associated Snow White with a daffodil. I know, I know. I'm weird. They are such bright, cheery flowers, and they push through the tough ground in the earliest part of the Spring. This reminds me of Snow White for some reason...

^ That's a cute association! I think Yellow would be Snow's favorite because it's often symbolic of joy and she's a very joyous character.

Or yellow. I always think she loves the red color.

Or red

Red seems to be "her color" in my opinion, since.....
*No other princesses have it as their main color
*Red is the first color in the rainbow, as she is the 1st princess
*It represents her red lips as well as the apple
*She has a red bow and red dots on her sleeves

I'm guessing yellow- the flowers she picks and the flowers she sends the animals to pick are most often yellow, which makes me think it's her favorite. :-)
