Use case: precise-object-edit. Input image is the approved brand mark, EDIT TARGET not loose inspiration. Preserve EXACT silhouette, proportions, shoulder tips, inner hollow contour, belly, all three supports, microtexture, front view and directional light. Change only material color and background. Recolor this dry finely textured sculptural mark into restrained botanical forest green: darkest inner folds approximately #263e33, principal matte surfaces #536b55, softly illuminated planes muted sage #9aa78c. Preserve the subtle thickness and concave/convex tonal structure. No saturated emerald, no jade translucency, no metallic or glass specular rims, no gloss. Warm neutral reflected light suitable for ivory paper #faf9f3. Remove the entire gray background and ground plane; provide GENUINELY TRANSPARENT RGBA background, including central opening and between the feet. Preserve only a very delicate neutral contact shadow if necessary, no gray rectangle or white halo. No text, typography, props, outlines or new details. Same composition as source. Artwork asset for small mobile brand header, refined and tactile, not flat color fill.
