・worry about someone's mood
・sensitive to someone's mood

「看臉色」可以用英語的 worry about someone's mood 或 sensitive to someone's mood 來表達。

Don't you always work while worrying about your boss's mood?
（你不是總是一邊看上司的臉色一邊工作嗎？）

These days, I'm always sensitive to people's mood, and it's not fun at all.
（最近，我總是在看人們的臉色，這一點樂趣也没有。）

希望對你能有所幫助。
