Okay, so this sketch was done a loong time ago. Back before Halloween maybe? I didn’t post it for a while because I wanted to have it in a single deviation with a BUNCH of other sketches of her character, but I’m still not quite sure how to do it..Does anyone know how..?  
But anyways this is Prism!  
I was actually making her more of a secondary/minor character with a strong role but it would be neat to flesh her out a little ^.
 
In optics, a ‘prism’ is a transparent optical element with flat, polished surfaces that refract light. When the light is refracted it lets loose different. Wavelengths, often creating a rainbow of different colors.  
So Prism!  
She is a mare of few words but is actually quite spirited. She has an enchanted crystal that comes with the curse of never being able to remove it. Yet the crystal allows her to change the color of herself to how she is feeling. I guess you could say that shes a mood ring!  
So strangely, this girls hide and mane is changing almost constantly!
 
The Crystal Empire has her as a spy of a sort. Which is why I made her a pegasus. I originally wanted her to be an earth pony but I thought the use of wings could be important aspect for a spy. While Prism learned the skill of being able to camoflouge herself to her surroundings she has a hard time concealing how she feels not just through her colors but her facial expressions.
 
So there’s more of her to put up I just gotta learn a way to make collages through photoshop or such : )  
Expect to see more of her and her character as well as a few other fun ocs in the future.
