Chasing the Rainbow is one of the hobby's most addictive collecting pursuits — you're hunting down every color parallel of a single player's card from a given set. Depending on the player and the product, a complete rainbow can include a massive number of cards, especially when autos are in the mix.
Some collectors focus on just the paper rainbow or just the Chrome rainbow, while others go all-in and combine both. Either way, chasing the rainbow is a commitment — but when you line up every color variant side by side, the visual payoff is unreal. It's one of those hobby flexes that speaks for itself.
