ing蓝颜ing红颜
[ing lán yán ing hóng yán]
蓝颜 (blue-collar relationship) typically describes a male non-romantic yet dear companion or friend who is very close and important, and 红颜 (red-collar) traditionally points to a female friend with strong platonic friendship bonds but also sometimes carries connotations like beauty. The “ing” here is possibly showing the status ongoing. So overall, it means 'being a cherished guy-friend while maintaining meaningful gal-pals connections simultaneously'.
