This entire vision of Jesus is of Jesus on earth but in Heaven in His full glorified state. To put it simply verse 16 says
And he had in his right hand seven stars: and out of his mouth went a sharp twoedged sword: and his countenance was as the sun shineth in his strength.
I don't know about you but I've never seen the sun shine black. This can be related to Jesus in Matthew 17:2 and Mark 9:2
Lets read from Matthew
Matthew 17:1-2 (King James Version)
Matthew 17
1And after six days Jesus taketh Peter, James, and John his brother, and bringeth them up into an high mountain apart,
2And was transfigured before them: and his face did shine as the sun, and his raiment was white as the light.
and now Mark 9
Mark 9:1-3 (King James Version)
Mark 9
1And he said unto them, Verily I say unto you, That there be some of them that stand here, which shall not taste of death, till they have seen the kingdom of God come with power.
2And after six days Jesus taketh with him Peter, and James, and John, and leadeth them up into an high mountain apart by themselves: and he was transfigured before them.
3And his raiment became shining, exceeding white as snow; so as no fuller on earth can white them.
Jesus in His glorified form is blindingly bright and brilliant. Not black.
As for what color Jesus is or what color you are what does the bible say............IT DOESN'T. And it doesn't MATTER.
There are only 2 colors that matter Red and White.
Isaiah 1:17-19 (King James Version)
17Learn to do well; seek judgment, relieve the oppressed, judge the fatherless, plead for the widow.
18Come now, and let us reason together, saith the LORD: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool.
19If ye be willing and obedient, ye shall eat the good of the land:
Seek the Lord while He maybe found.
