A study from Finland presents a visual display of how our emotional state can also affect our physical state as shown via color mappings:
The immediate stand outs are that the state of being happy elicits a glow over the entire body, followed by feelings of love as a close second. I guess that means someone who’s both happy and in love must have an inferno of an overall glowing warmth/sensation. =)
The study also revealed this color mapping of people is consistent across different nations and cultures- showing once again that we are all more alike than different.
Details of the study can be found here.
