Exaggerated Fear/Blue Blush (Facial Expression)

When trying to create facial expressions for characters, I've tended to notice it has trouble depicting fear or anxiety. In cartoons or anime, when a character expresses shock or fear, their face may gets this sort of blue gradient across their forehead. I don't really know how to describe it, but I like to think of it as a blue blush. I wanted to recreate this expression for characters.The trigger word is: w0rr13d3lu3l1n3You can subsequently tag: blue facial hue, scribble eyes,The tags I used in each of the images are as follows:w0rr13d3lu3l1n3, scribble eyes, (blue facial hue), disgusted,w0rr13d3lu3l1n3, scribble eyes, (blue facial hue), scared,w0rr13d3lu3l1n3, scribble eyes, (blue facial hue), anxious,w0rr13d3lu3l1n3, scribble eyes, (blue facial hue), scared, screaming, wavy mouth,w0rr13d3lu3l1n3, closed eyes, (blue facial hue), sweating, nervous smile,I removed scribble eyes from some prompts, and you can as well if you wish.For a more classic look, you can also tag "wavy mouth" or "no pupils." However, they are tags and not triggers. If someone knows what this is referred to as please tell me.
