The middle of the eyebrows is black. Is Tang Yin black? Will it bring bad luck for Tang Yin to be black?

This is the so-called blackening of Tang Yin. In fortune telling, it is superstitious to say that Tang Yin is black and unlucky. There is no such thing, but if Tang Yin is black, it may be anxiety, listlessness, staying up late, poor sleep, bad mood or a hint of metabolic imbalance. Keep a good mood. I hope my answer can solve your doubts.
