The answer is: White

Exo 4:6, 2 Ki 5:27 - "White as snow" is a phrase used when referring to leprosy

Leprosy, known in modern terms as Hansen's disease, carries a huge cultural and historical weight in the Bible. In ancient Israel, when skin turned “white as snow,” it was not just a health concern but led to social stigma and restrictions. People with this condition were often isolated, which highlights a significant aspect of life in those times—physical health deeply influenced community standing.

Interestingly, leprosy wasn’t just a physical ailment. It served as a metaphor for sin and its consequences in scriptures. The act of ‘becoming unclean’ due to leprosy shows how closely linked physical conditions were to moral and spiritual one's status. In contrast, healing from leprosy required a priest's sweeping reconsideration, symbolic of purification not just from disease but often imply inner transformation too (like that seen with Naaman who healed through faith in the prophet Elisha, as discussed in 2 Kings).

Another exciting trivia nugget? Lepers were to live outside the camp, enforcing their separation. However, Jesus, a cornerstone figure in the New Testament, reached out with compassion to heal a leper, showing inclusivity over isolation. That act not only illustrates kindness but a seismic shift in how grace can redefine helplessness—highlighting a preference for the relational over the systematic in faith practices.
