Not dark - olive toned, like any other Mediterranean, or rather, European, as per the premise of your meme.
For you to throw such a hissy fit about knowing historical knowledge yet go on to spout misinformation about that which you already supposedly know is hilariously hypocritical. Europa stretched from present day Southern Europe to the Near East, Middle East, and Northern Africa, surrounding the Mediterranean Sea - the water between the land. The barbaric hinterlands entered the map much later.
"Brown" Midle Easterners today come from an admixture of African brought in as slaves. While present back then, the numbers were so few that they were easily identifiable as they stuck out, as pointed out in the Bible.
"the bible has references to Hebrews being more light skinned compared to other Mesopotamian cultures of the area."
No, it doesn't. You yorself contradict this by stating Mary & Joseph passed as Egyptian.
"The only one questionable is Egyptians, were they black? Historical references claim Egyptians were dark skinned, but were they black or more like Arab. This is a debateable topic. However, I tend to believe they were both."
Um, they only painted murals of themselves, you confounded twit. They looked like their descendents today because that's who they are. The Nubian conquest and Dynasty brought in Sub Saharan African types, as well as did slaves. This was also presented in the murals. Since nobility, particularly women, didn't toil in the sun or venture outdoors much, they were usually pale, again, as seen on their murals.
Sudan? Ever hear of Nubia? Kush?
Next time you're going to have a major cradiac arrest, look up your facts. Bible school is cute, but hardly scholarly, given the agenda and the Northwestern Eurocentric Jayzuz revisionists that use it as a means of brainwashing uneducated dolts with high Ignorance Quotients.
