yellow light

I am kind of confused, why do i Look so much better in eyllow light? I mean everything about me looks so much more "healthier?" my skin, my eyes. I dunno when im not under yellowish light, i look sickly? my eyes look malnourished, my skin not glowing but palish.   Im not sure how to get this yellow light look? I exercise a lot btw, and eat 5 meals a day, lift free weights.  I am asian btw.  Thanks!
