I do tech support and documentation for a software company and our devs half-jokingly refer to that phrase as a prelude to an a customer asking something impossible. I'm using it because I think it fits here.
I was reading the about asymmetrical ideas and it occurred to me that many comic and anima characters might have reasonably standard hairstyles, but non-standard colors. I'm not talking about all their hair, I'm referring to odd flairs. The most iconic I can think of is Rogue's skunk strip.
I do not expect the developers to conceive of every possible pattern and add support for that to all meshes. That would be a nightmare to create and maintain. However, it might be possible to allow something like a paint overlay. Back in Maxis' Sims 1 and 2, all the clothing and such was BMP files wrapped around a mess. So I was wondering if the hair could be done similarly. Allow a color choice that opens a bitmap like editor or one that has line, spray and file type tools to literally paint/color the desired appearance. Bonus if this could be added on top of the the original coloring. Maybe consider this a hat-like accessory.
Yes, I understand it would be a massive project.
Yes, I do not expect it at launch or any time soon
I see this as something you might consider adding multiple releases after launch. I just thought it would be a nice addition and really let the artistic types go wild.
I wanted to post it while I was thinking so the devs could at least think about it.
