Sounds like a dreamy project—start with a base of deep forest greens, then layer on muted golds like honeycomb and amber, add textures like rough bark, soft velvet leaves, and a splash of crisp, dry leaf silhouettes. Play with gradients: cool charcoal shadows against warm amber highlights, sprinkle a hint of slate gray to ground the palette, and sprinkle a dash of rusted copper for that autumn kiss. Keep swapping until the transition feels like a gentle, inevitable sigh of the season.
