Red / brown hairs

Yeah if you look closely at those pistils you will see they are darkening from the core all the way down through the pistol. And the orange are kinda evenly spaced here and there across the buds. This is what you want to see. It will probably pop some fresh ones here and there also. If your pistils are burning you will get a darker brown shade that affects whole clusters of pistils at once killing them from the tips down. Your buds are looking pretty nice.
