Thanks, Beverly.
If you guys were going to describe the hair colour of Sam, Dean, and Cas (deliberately not asking about the actors, because we know it doesn't have to carry over)?
To me, they're light brown, brown, and dark reddish brown (he needs similes).
Similarly with their eyes--green like the sun coming through the leaves, hazel (that's what green/brown is, right?), and crystal sea blue (I know, it sounds cheesy, but they look like such a different blue to me, and trust me, I keep looking).
Also about Dean's eyes--our lids cast a shadow on our eyeballs, and the way he's configured, his brows often leave a shadow that we can see hitting *under* his cornea, and it gives a delicate super 3D effect. Which is a bitch for me to draw...
