The Inuits, whom the Water Tribe is derived from, were dark-skinned. If we were to get scientific about it, the ozone is thinner toward the poles: hence, the need for more melanin production.

Also, Chinese/Japanese people live in tropical/subtropical zones, but they're not necessarily dark-skinned. It honestly depends on exposure to sunlight, genes, and weather conditions.
