It is not uncommon for anatomy regions of the vulva to have similar, or complementary colors. Even if all regions contain a shade of the same color, the color tag for each applicable region should still be used. Anatomy that is not visible should not get a color tag.
Vulva (blue_vulva)
The color of the vulva itself, or in the case of anatomy with outer, and inner labia folds visible, this refers to the color of the outer labia folds (also known as the labia majora, or vaginal lips). The color of the inner region of the vulva, usually the inner labia folds, the region that contains the clitoris. This region is sometimes called the vestibule (entrance) into the vagina. The color of the erogenous nub nestled between, or above the labia, situated near the top of the vulva (or the bottom if the character is viewed from behind). Sometimes the clitoris will be hidden inside the vulva itself.
