My fursona, Chroma, in pony form!
I had a few things in mind that I just typed up. Sorry if any of it is redundant, conflicting, or cheesy. I don't write too often. It's a work in progress >_>
She sounds more and more like a unicorn as I write this, so until I fix it or draw her again I'm just gonna pretend she has a nubby horn and it's hidden under her hair
Chroma's special talents all relate to color, mainly her ability to change the colors of things around her. She does this often with her hair and fur-markings, sometimes to reflect her mood and sometimes just for fun. Occasionally she might do it involuntarily when overcome with emotion. She lives in Ponyville, where she grew up, but is currently studying the arts in Canterlot to find out what she wants to do with her life.
She doesn't dress heavily too often, but loves to wear accessories. She is a good student and is responsible and kind, but can often be a bit of a klutz and a scatterbrain. She can also be stubborn at times and is very indecisive. She'll change the color of something dozens of times and still feel unsure about it, even if they all look fine. Her indecisiveness often makes her flexible when making plans with others, but when they ask for her personal opinion it often results in an "I don't know" or "I'm fine with anything!" Even when she has preferences, she often likes to do whatever everyone else wants to do to make them happy. When she's grumpy she can be blunt and irritable, and usually wants to be left alone to herself. She usually likes to put of a happy face though, so she's pretty cheerful most of the time.
She isn't the most talented, but is a bit nerdy and enjoys art, technology, and digital media. She tends to focus too much on perfecting tiny details, often taking a lot longer on things than most people on simple tasks and unnecessarily wearing herself out. She enjoys time alone, is a bit shy around everyone but her closest friends, and gets embarrassed easily. Her responsible and caring demeanor makes her a somewhat motherly though, so some of her close friends often come to her when they need help.
How does Chroma change the colors of things? Is it something she has to concentrate to do, or can she do it on a whim?
I'd say that she has to concentrate to use her powers, but she's slowly getting better at it. It doesn't usually take too much time, but she does need to focus for a little bit. Sometimes when she's working on a project or something she can get 'in the zone' and use it more rapidly. Things with very complex color schemes can be much more difficult for her to work with, and she doesn't usually use it on others' things without permission either. Sometimes she uses them on accident when she feels any kind of intense emotions, but they don't usually cause much harm.
Oromo seems really neat! They could probably get along
