黛深浅
[dài shēn qiăn]
Dai (黛) refers to the black or bluish-black color of eyebrow makeup used in ancient China, symbolizing elegance and mystery. Shallow or deep refers to the varying intensity of this color, thus '黛深浅' represents a graceful, enigmatic person whose moods are hard to fathom, much like the subtle shifts in depth of this unique shade of makeup.
