Reader Question: Dupes for Chanel Foundations

One of my lovley readers, Maggie, is looking for some assitance with regards to duping her favorite Chanel foundations, one of which the shade isn't made anymore.  I did some research at the department store counters, but seeing as I am a mineral-makeup girl, I thought I would see what you all thought!

Mat Lumiere Fluide in Porcelaine or Ivory

or

Teinte Innocence in Gentle Ivory (Teinte Pur Mat in Fawn was the best match EVER but they don't make it anymore).

Maggie and I would both love to hear your thoughts, experiences, etc...

High End and drug-store brands are both welcome!  Thank you all so much - you're the best!
