Color Matters

Effects that scale with the number of colors among permanents, mana, or cards, or that gate abilities behind specific color requirements. Bloom Tender and Faeburrow Elder produce mana for each color among permanents you control; Jodah, Archmage Eternal and The World Tree care about having all five colors available; Sphinx of the Guildpact is all colors; All Suns' Dawn and Niv-Mizzet Reborn fetch cards by color identity. Distinct from color.color_hoser, which asymmetrically punishes a single chosen color rather than rewarding color counts, and from color.multicolor_payoff, which specifically rewards gold cards rather than scaling with raw color counts.
