‘吝色’ literally combines 吝 (lìn), meaning 'stingy' or 'grudging', and 色 (sè), meaning 'expression' or 'facial color'. Together, it describes a visible, unwilling facial expression — often a tight-lipped frown, narrowed eyes, or tense jaw — that signals reluctance, especially when asked to give, share, or help. It’s not about physical stinginess alone, but the unmistakable look of emotional or material resistance.

This noun is used mostly in written or formal spoken Chinese, often in descriptions of someone’s reaction in social or moral contexts — for example, when refusing a request, parting with money, or yielding to pressure. While not archaic, it carries a slightly literary or critical tone, implying disapproval of the person’s attitude. It’s rarely used in casual speech among friends but appears frequently in essays, news reports, and literature depicting moral dilemmas or interpersonal tension.
