It is to my understanding that the "tinge" feeling is caused by the increased blood flow and release of adrenaline as a result of emotionally stressful situations. I think the intensity of the feeling depends on how severe the situation is. For instance, occasionally I get a mild "rush" when watching or reading something that I become emotionally invested in. This feeling only lasts for a few seconds and usually feels, at least to me, like a cold chill running through my veins. For me, it usually occurs at points of high drama or actions sequences.Originally Posted by Sapphire
