红颜祸水蓝颜祸水
[hóng yán huò shuĭ lán yán huò shuĭ]
A saying derived from ancient Chinese culture meaning both beautiful women ('Red Beauty' as disaster) and handsome men ('Blue Handsome' as disaster) can be sources of trouble or chaos in others' lives. This implies that one should be wary of excessive attraction leading to bad consequences.
