You are right about the stars and my statement was unclear. The elves awoke as Varda made new and brighter stars, and it is stated that "their eyes beheld first of all things the stars of heaven. Therefore they have ever loved the starlight" When looking in the Silmarillion, it seems that they primarilly loved the stars and aspecific preference forthe moon is not mentioned. However, the moon came first (as the elves, compared to the humans) and traveled over the sky several times before the sun first appeared; "Isil was first wrought and made ready, and first rose into the realm of the stars, and was the elder of the new lights, as was Telperion of the Trees. Then for a while the world had moonlight [...] Tilion had traversed the heaven seven times, and thus was in the furthest east, when the vessel of Arien was made ready" and "the Sun was set as a sign for the awakening of Men and the waning of the Elves, but the Moon cherishes their memory" Why it matters? So, in my opinion, that the elves may be fair or perhaps pale in the skin makes sence symbolically due to their relationship to the night and the stars (and perhaps the moon). Also, in humans, there tends to be a relationship between the sun exposure of an area and skin color but I don't think we know how this affect elves (how their bodies work, some born before the sun was created, living for very long time, etc.)
