His hair glows red because of his Semblance. The sword glows red too because of Aura. The sword's blade is red-colored because it's got Fire Dust. And the fire slashes he makes on ocasion are because of said Dust. Huh, I mean, now that you mention it their Semblances are kind of similar. Given they already established that a Semblance can be passed along familial lines, it makes me wonder if those two are related. Perhaps someone has already suggested that. It would be consistent with both Raven and Adam using masks reminiscent of Grimm.

So Sun and Blake are related?

The more pleasant option is that some people just have similar Semblances. Also, hereditary Semblances were established as being extremely rare at best.
