There are 7 types of rarity for the albums, they are: black, yellow, green, blue, red, purple and rainbow, with black being the most common and rainbow being the rarest. The evaluation result has certain rules depending if the album is weapon-based or part-based.
Generally speaking, the rarer the album color is, the more parts slots the weapon will have once evaluated. Though there will still be cases where rainbow albums will give a weapon with only 5 slots instead of the full 6 slots.
When it comes to rare tags, they can't come from albums with black, yellow or green colors. The lowest rarity possible is blue.
Weapon level is RNG based, even if the album is of rainbow rarity, there will still be cases where the weapon received comes at below LV. 100.
