Colors isn’t really an issue. You can fix that in postwork.
Elf options ? I don’t actually understand what you mean. I believe you have a 5th ed specific issue in mind but it’s not that obvious to others.
Horns may be a thing, although I’m not sure I’d hold my breath on that one. Unless someone wants to design a pack specific for horns (or tiefling horns, which is kind of a mystery to me, I’m an AD&D/OSR player, I have 0 experience with Tieflings, eheh ^_^ ).
Dragonborn has already been asked and answered. This would require complete packS all by itself. Nobody worked on that one as yet.
Anyone wants to give better answers ?
