I'm on my third restart now, decided to see if I could make a drow look the same, and you can, you can pick the regular elf colours for everything except the eyes.
Green dragon drow with green scales, hair, tattoos and scales.
I find it funny that everyone still recognizes me as a drow though even though I look like a high elf. Reason for the change was I don't actually need the extra cantrip slot, you already get plenty on casters, and the superior nightvision is a lot more useful, my main reason for picking elf was to get the perception bonus which both high elf and drow get.
Also trying out Dark Urge now, you can't change the background so I had to drop +2 in deception, but I fount it still works well with the CHA bonus and guidance.
