The Devil in the Details
Hmm!
I hadn't considered using red as more than just a tiny detail.
I know there's a word for it and it's not 'enhancer' but I just can't for the life of me figure anything else out. The book is a great idea, though!
It's possible I'll have to go with like, short-shorts or a short skirt to fill in that lower torso gap. I know I ran with an avatar like this before I took a break from the site, but I have no idea anymore what I did for that problem.
I believe the term you are looking for is "accent color" :3
