I know EXACTLY what you mean! Yellow lighting or dull lights always bug me, because I like to see clearly, but when I am in a panic episode, they make me very uncomfortable and anxious. I feel almost dizzy or "off" which causes me a lot of anxiety. I was at a very nice restaurant, a seafood buffet, but could not stand it because the dim, yellow lighting was making me sooo anxious. I commented to my mom that perhaps they do it on purpose, to keep people from making to many trips to the buffet. It certainly caused me to lose my appetite pretty quickly. :)
