I agree with OP. I stopped all Q e-mails because they got cumbersome. Some people are watching on their phones or tablet.
I would think the foundation colors shown on skin would be the first place they would start, before eye shadows and blush.
Looking at Jacquie, it looks like it is a yellow based, and she as in the medium light. That is the only reference on skin we had at the outset of the show. Then maybe one model said what color she was in.
That is the vendors JOB to make sure colors are shown and demonstrated.
