Sedune

Sedune is a kayeni, much like Tessida. One of the interesting items of note about kayeni is that they possess an epidermal layer just below their very thin melanin layer that is highly reactive to adrenaline, seratonin, and various endorphins. In a nutshell, kayeni skin color changes with their mood. Sedune is an activist singer/beat poet, and when she gets fired up while reciting her poems or singing, her skin undergoes impressive hue shifts. To enhance the effect for her audience, she has gotten geometric designs tattooed across her entire body to mask and accentuate the changes. The result ends up being a scintillating kaleidoscope effect dancing across her skin.

On a technical note, this image demonstrates why I really should have taken a color theory course at some point. Also, sticking to a particular style likely would have been helpful.
