Hebrews Had Dark Skin

Why are there so many references to the Hebrews having dark skin, and none of them having white skin in scripture?

Why were they mistaken for Egyptians from the time of Joseph, up until the Apostle Paul began preaching? The debate as to whether or not the original Hebrews had dark skin, can be settled using scripture and history. There are verses all over the Bible that give us an indication of what the original Hebrews looked like, before they began to mix with the invading European nations.
