柔和的中性米色和粉笔白色粗糙背景，带有光滑的风化纹理和褪色的笔触细节

beige and chalk white grunge background with gentle weathered tones, subtle brushwork, and delicate worn textures. The surface resembles aged plaster or sun-faded wall paint with softly blended patches and minimal high-contrast details. Thin etched marks and faint layering provide quiet depth, making it excellent for calm abstract compositions and airy textured designs.
