Bold vector illustration of a simple green willow tree, flat design with solid fills, clean SVG paths. Isolated on a solid background, centered composition. Drooping, graceful branches with elongated leaves, stylized yet recognizable. No shading or gradients; thick, smooth outlines define the silhouette. Palette uses vivid emerald greens for foliage and a slightly darker green for trunk and branches. Ultra-clean geometry, crisp corner joins, scalable for icons or logos. High-contrast, minimal detail to preserve legibility at small sizes.

The image shows a black and white silhouette of an olive tree on a white background. The tree is depicted in great detail, with its branches and leaves clearly visible.
