blue with shock
If something truly traumatic occurs to a character, or they are mortified or embarrassed beyond all reckoning, the upper half of their face, or even all of it, may turn blue — at least until they recover.
A variation on the effect takes the form of a set of wavy blue lines that radiate upward from the character's head and shoulders in a manner reminiscent of a Battle Aura. Darker-blue lines streaming down their eyes like very straight tears optional.
It's usually used for comedic effect, and serious situations.
