事情是这样的，我偶然查到rage的2个词组：purple with rage VSdark with rage我第一时间想的是，前者表示非常生气，起到脸色发紫；后者也是非常生气，但是起得脸色阴沉。
但因为我是一个雅思写作老师，我清楚自己作为一个中国人，常常会形成自己的错误理解。所以，我还是到国外网站问了一下。
1 His face was purple with rage.
2 His face was dark with rage.
Is there a big difference between them?
这是第一个回复：
1. "His face was purple with rage."* Imagery: Face turning purple due to intense emotions.* Connotation: Explosive and immediate anger.2. "His face was dark with rage."* Imagery: A shadowed or clouded expression.* Connotation: Brooding or simmering anger.Summary:* "Purple with rage": Intense, visible anger.* "Dark with rage": Serious, controlled anger.
这跟我前面想的完全一致。我还挺高兴：我猜对了！过了一会儿，我收到另一个回复：
I'm anativeEnglish speaker andI don’t think there is any difference between these phrases.Also, these aren’t common at all.Maybe things you would see in literature.It’s more common to say 'red with rage' also, but I wouldn’t naturally use this phrase.
后来点进2个回复的账号，前者来自Belize（伯利兹，一个中美洲国家），后者来自漂亮国。
