Raritys are given as it's spawn rates. Colours given to rarities are roughly based off % spawns. Spawn locations are listed in order of the games progression.
Mythic rarity is for pokemon that can only be spawned once through completing a quest/series of missions.
Unique rarity is for pokemon that solely spawn in a specific area. These spawns have double the regular shiny rate so they would be ideal for shiny hunting.
Event rarity is for pokemon obtainable through limited-time events. Hovering the "event" tag will let you see when that pokemon was available and how.
