Legend
I take it the Drow are black-skinned in the sense of fertile soil, thus a fey eartlhly source of life and technology, that was always subterranean. Lolth worship is a spider-demon cult that corrupted this. But Drow who preserve earlier animistic traditions or explore other religious traditions are mainly Good. They tend to revere the earth as an all-mother.
There is no color coding, but conspicuous symbols of spiders usually display a membership in the spider-demon cult.
The Drow in the Feywild tend to be Good.
The Drow in the Material tend to be spider cult, who fled from the Feywild.
Incidentally, I view Wood Elves as a faction of Drow who initially belonged to Lolth and fled to the Material, but then realized how Evil she was, and split away, but remained in the Material.
One thing I'm trying to do, and I haven't had a lot of success so far, but I also haven't had a good chance to focus on it, is to make spiders more important to all elves, as well as just reunify the elven cultures. Mostly just to do something different.
Problem is, I haven't figured a decent way to make spiders more generic and less evil. So, I'm still mulling it over and trying to do some minor research for ideas
