Pure Anada foundations with COOL undertones are designed for caucasian ladies with decidedly pink undertones. This is not to be confused with "reddness" that may be present on ANY skin undertone.
A COOL undertone can be seen on the neck and jawline, as a soft pink skin color. The lighter shades in the cool range "Arctic Alabaster" and "Prairie Rose", are for very fair ladies. They find all other shades of foundation too "yellow" for their skin tone. The deeper shade, "Beige in Banff", is for the lady who has a deeper complexion with no golden undertones. They may naturally exude a deep pink complexion.
