Questions about signature club A

I am wondering why Adrienne only has two shades of foundation. Does anybody know? There are soooo many women of different colors. From personal experience her foundations aren’t forgiving at all. Has she ever had different colors other than the fair and medium?

My next question refers to her foundation as well. Why do you suppose she NEVER calls foundation FOUNDATION? She always calls it makeup. I’m wondering if this something from way back years ago. I’m not dogging her. I love to watch her. But for decades I have wondered about these two things. I wish somebody could enlighten me. Thanks ladies.
