Since you state you've looked in Bibles, I'm assuming you're interested in the answer from a Christian viewpoint, so that is what I will provide. Please let me know if you had something else in mind.
God Himself, the Father, the Creator, the Almighty, is neither black nor white because he is not a human person. The Bible says in John 4:24 "God is spirit, and his worshipers must worship in spirit and in truth."
However, in order to save the world, God sent His own essence, His own nature, His own Spirit into the world in bodily form, in the person of His only begotten son, Jesus Christ. Jesus was both fully God and fully human. We know he was human. The historical record, from both the Bible and outside sources, verifies his existence. We know he is God because he said so. ""I tell you the truth," Jesus answered, "before Abraham was born, I am!" (John 8:28) This statement echoes what God said to Moses in Exodus 3:14, "God said to Moses, "I AM WHO I AM. This is what you are to say to the Israelites: 'I AM has sent me to you.'" Therefore, Jesus saying "I am" demonstrates that he said he was and is God.
In his humanity Jesus was born a man of Hebrew (Jewish) descent. See Matthew 1:1-17 and Luke 3:23-38 which trace his genealogy on both his earthly father's and mother's sides back to Abraham, and to Adam, the first man. The Bible gives no physical description of Jesus, except to say that he was not attractive. The prophet Isaiah said of him, centuries before he was born, "He had no beauty or majesty to attract us to him, nothing in his appearance that we should desire him." (Isaiah 53:2) But there are no details given about his height, or weight, or hair color or eyes or any other descriptive details. There has been much speculation and debate over the centuries as to what Jesus actually looked like. There are paintings of him as white, and black, and everything in between, according to the imagination of the painter, and many books and articles proposing all kinds of theories, and possibilities of every race. None of them can be taken as fact, because we simply do not know.
Nevertheless, because we do know that Jesus was a Jew tracing his bloodline back to Abraham and Adam, we may reasonably assume he resembled other Jews, who have been shown to be genetically linked by DNA, and are racially similar. Current research has been published that purports to show DNA links between Jewish people that might establish them as their own race, although this is controversial. Historically, Jews have been considered a subset of the Caucasian race, and this may still hold true despite the newer research.
Regardless, there are so many individual variations among even ethnically pure Jews who can trace their ancestry back in an unbroXXXXX XXXXXne to the historic Hebrew people, that it's impossible to say with certainty whether Jesus had black hair, or brown or red, or brown eyes, or hazel or green, or any other detail of his appearance. However, we might reasonably assume he was not of the Negroid race, so he was probably not black as we understand that term. Even so, there is some suggestion in the Bible that he may have had a black ancestor or two, but that is speculation and unproveable. And since there is some question as to whether Jews are actually a subset of the Caucasian race, or a separate race with its own characteristics, we can't definitively say that he was white either.
Therefore, since we simply don't know for sure what he looked like, or what his actual race was, apart from his ethnic identity as a Hebrew, the answer to your question is two-part (from a Christian point of view):
1) God the Father is a Spirit, and thus is no race at all;
2) God the Son, Jesus, was an ethnic Jew of unbroXXXXX XXXXXne from Adam. However, due to scientific disagreement about whether the Jewish people are a separate race, or a subset of the Caucasian race, we can't say with any certainty that he was white, although, despite the possibility that he may have had one or more black ancestors, we can nevertheless reasonably rule out black or oriental.
It may be that Jesus' race was left deliberately unstated and unproveable so that all people might be able to identify with him as the Savior, as He as God created them all.
