However, in the cases of mutations which are truly "cosmetic" then sexual selection can also play a big role. If the other drow think that black skin is attractive and pale skin is ugly, then drow with black skin will be better at passing on their genes. | |

But the elves were only an examples there many more cases that I will need to study how to make more credible. | |

Added further explanation to the expand of the question

Color, as said above in an answer, is a mechanism of adaptation to the environment. In cases when everything is blind and it is always absolute darkness around color responsible parts of DNA are not being expressed to save energy (prevent useless spent of it). | |

Unless those minerals produce “dark” light en.wikipedia.org/wiki/Ultraviolet. As far as I remember the texts of Drizzt's early ages they use infravision 95% of the time or more, which means there was not enough of any kind of light specter in most areas and darkvision requires to have at least minimal light source (even cats won’t be able to see in a place where there is absolute darkness). | |
| Sep 22, 2017 at 19:02 | comment | added | Hirokuro | FR is a fantasy world, so there might be crystals that produce UVR, but in RL there are no such crystals. Minerals might produce light though but only when exposed to UV specter or being broken/scratched/etc. (energy being set free and as free energy needs to take some form it usually takes a light form, for example during explosion appears a fire, which is actually just a shape of energy of this explosion). en.wikipedia.org/wiki/… | |
| Sep 22, 2017 at 15:49 | comment | added | Henrique César Madeira | What if the Drows lived underground like in FR, but the place has minerals that emit UVR enough for the ebony skin be needed, I don't know if such minerals exist or are at least theoretically possible. Or the food at the local has something that stimulates the production of melanin? | |
