I mix Fuschia and Petunia convertible colors together and it gives me the perfect pink flush for me. No ruddiness at all.
It sort of depends on your preference.
I also have peony and it's a more subdued shade, although I still use it very sparingly. I'm pretty sure that it could make you look a bit ruddy if even a little too much is applied.
I would say it prefers on your preference. Peachy or Pinky? Vibrant or subdued, etc.
