Origin

The character combines "豊" meaning abundant or rich with "色" meaning color or appearance, creating the idea of a rich, abundant coloring or lustrous quality. The left side suggests fullness and plenty, while the right side indicates this abundance relates specifically to visual appearance and hue. Together they express the concept of something that has a deep, glossy, or charming visual quality—the kind of attractive sheen or colorful richness that comes from abundance of color and light. This compound logic naturally leads to meanings like luster, glaze, and charm.
