Step 1 : Introduction to the question "1. When embarrassed about something, your face is likely to be which of these colours?"
...1. Blue 2. Green 3. White 4. Red Being embarrassed can cause the release of stress hormones, which dilate the blood vessels near the surface of the face, making you blush. The same happens with exercise or anger, both of which can cause facial redness. To be blue in the face means to be making a great effort, and someone who is white faced could be ill or shocked, with the blood having drained from it. To be green faced is to be feeling nauseous.
