Using this palette

Two genuinely different material states in one palette, which is unusual for this dataset — copper starts warm orange-brown and oxidizes over years into a cool teal-green patina, and rather than picking one, this palette shows both, split roughly down the middle. That means it functions almost as two sub-palettes: use the warm half (#7A3B1D, #B5651D) alone for anything wanting metal warmth, or the cool half (#4A7C6F, #7FA894, #D4E3DA) alone for something calmer, or blend both for a genuine 'aged metal' effect. #7A3B1D and #4A7C6F both carry white text reliably. Suits architectural, heritage-restoration, or artisan-metalwork branding.
