Is it normal for my Double Yellow Headed Amazon to have Red on her head?

[brighterdaysaviary]

I'm just curious if this is normal for my DYH to have red on the back of her head? There are splashes of red mixed in with her yellow. I also believe she is a Magna DYH because she has yellow on her legs and she has yellow on the tips of her wings, she also has red on the tips of her wings. She is 10 years old.
