Booster Pack Rainbow

The Booster Pack Rainbow refers to the cycle of eight background colors on Booster Pack sleeves followed by each series of OCG and TCG Booster Packs since the introduction of Series 4 with the release of Soul of the Duelist. However, in OCG this trend started in second series, with 9 colors in same order, and ending with brown. Starting with fourth series, they shrunk to eight booster per series, dropping brown. This is untrue for TCG, as prior to Soul of Duelist TCG boosters were composed of two OCG ones.

So far, every "Green" set has had the word "Duelist" in it since Series 4, and has either introduced a new gameplay dynamic, or elevated a previous mechanic (Soul introduced "LV" monsters, Power introduced fast-paced Fusion strategies with "Future Fusion" and "Overload Fusion", Genesis introduced Synchro Monsters, and Revolution augmented Synchro Monsters by introducing Synchro Fusion Monsters like "Dragon Knight Draco-Equiste"). First boosters of second and third OCG series had Ruler in their name, instead.

Likewise, a trend has been seen with the "Black" and "White" sets. Like their name, the "Black" sets introduce predominantly DARK monsters that alter the metagame at the time of that set's release (Shadow of Infinity released the Sacred Beasts, "Demise, King of Armageddon" and "Treeborn Frog"; Phantom Darkness released "Dark Armed Dragon"; and Absolute Powerforce released "Battle Fader"). Conversely, the "White" sets introduce predominantly LIGHT monsters designed to counter what was introduced in the prior "Black" set (Enemy of Justice released numerous monsters used in Counter Fairy Decks, Light of Destruction released "Honest" and the "Lightsworn" Archetype, and The Shining Darkness released "Herald of Perfection").
