Pack color?

Just curious if anyone puts any thought into pack color when you purchase? Most of the time, black is the only option, but in my case I have some options. I've heard the argument that brighter colors are better from a safety/emergency standpoint (being seen, signaling).

I'm continuing to research a new combo AT/backpacking pack and the model I'm considering (Mystery Ranch Glacier) has 3 options - a burnt orange, a midnight blue, and muted/earthy green. I'm leaning toward the orange but was hoping to get some input..

Thanks!
