Google translate badly handles the Taiwanese Chinese text (with a little help from me to make it less bad):
Multi-purpose palette of colors, can be used individually, can also be mixed with a brush.
Actual use, just as visual color! Makeup artist suggested that orange, yellow and pink can be mixed with the brush as a blush, or a dampened trimming brush with a brown trimming, and the blue, in addition to painting cute small dots on the face, can also be used as eye shadow.
I'm guessing that "trimming" is a bad translation for "lining", as in eye liner.
Anyway, it sounds like the MAC MUAs are not suggesting swirling >every color< together, just the pink, orange, and yellow; and are suggesting using the brown and blue individually, as our own Mac-Guy has been telling us.
Still i'm curious to see just how muddy or odd the colors are mixed...
