Re: why do some people's eye color change?

Rafaella,  Your eye color is not actually changing but appears to change.  
Depending on the color of clothing and surrounding area, your eye color is 
"picking up this and then reflecting the color" and thus appears to be 
changing.  Some eye colors do this more than others also.  Brown eyes don't 
appear to change much while lighter eye colors do.  If you are wearing 
brighter colors this too may enhance that effect of your eye color 
changing.
