the rainbow type is weak against bug, ghost, poison, and dark types.
it is strong against water, fire, flying, dragon, and steel.
it is resistant to rock, and fighting.
it is immune to fairy, psychic, and ice.
and it is neutral against normal, grass, ground, and electric.
the rainbow type usually buffs a Pokémon's base stats by around 100 points in its top 3 strongest stats contrary to its normal counterpart.
and Celesteon is a pure Rainbow Type. it has the ability known as "rainbow randomizer", which randomizes 3-5 type weaknesses, type resistances, type immunities, and type advantages, making it almost completely sporadic. it has 4 signature moves.
Rainbow Raid: a move that calls upon all 8 eeveelutions and delivers a rainbow blast from each eeveelutions from the sky that merges together, almost akin to the z move of lunala. it also increases the damage by 100 depending on how many eeveelutions are in the party of the user at the time upon using it. half of however much damage is dealt is taken as recoil. it has a default pp of 5, an accuracy of 75%, and it is a special category rainbow type move.
Spectrum Strike: a move in which the user strikes the target with concentrated Light energy. User's special attack gets boosted by one stage. deals extra Damage in Spectrum Terrain(a new kind of terrain). it has a default pp of 15, an accuracy of 100%, and is a special category rainbow type move.
Luminescence: a move in which the user Smashes its horns/claws into the ground, creating a burst of Rainbow aura, damaging all adjacent foes, Summons Spectrum Terrain, and eliminates all field hazards on both sides. it has a default pp of 10, an accuracy of 100%, and is a physical category rainbow type move
Multi Light: a move in which the user heals half of their Max Hp, while boosting special defense by one stage. it has a default pp of 15, has an accuracy of 100%, and is a status category rainbow type move.
a new terrain: Spectrum terrain

most of the data of the rainbow type came from the fanmade game called Pokémon Anachron, I just altered it a little bit to make it a little improved.
