My defaults, then, are 1: dark brown, hazel; and 2: dark blue, light green, dark grey. I picked them out of one of Shadyline's sets. She's my favourite eye creator :D
My default skins are from multiple creators, and I only chose tones that exactly matched the Maxis ones. After that, I geneticised the rest of my skins based on the defaults. Since I finished that project a few years ago, I've downloaded skins only once or twice, because the hassle of geneticising just isn't worth it. When I get pre-geneticised skins, they rarely fit in with my own set and I have had births ingame where the baby's skin doesn't necessarily make sense.
Boring post :D I've got half a Henderson update ready, though, so keep an eye open for that possibly next week.
