Use the uploaded product photo as the exact source. TASK: change the colour of only the [BỘ PHẬN] to [MÃ MÀU HEX]. Recompute the shading correctly for the new hue: keep the same material finish, the same specular highlights in the same positions, the same reflection pattern, the same shadow shape and the same surface texture, adjusting only the base colour and its natural tonal range so it reads as if the product was manufactured in this colour. Preserve every edge and seam exactly; do not let the new colour bleed onto adjacent parts, the background or the shadow. KEEP UNCHANGED: all other components and their colours, the label artwork, the background, the lighting setup, the camera angle, the crop and the aspect ratio. DO NOT: restyle the product, smooth the texture, adjust global exposure or contrast, add gradients that were not there, add text or watermark. The result must be indistinguishable from an original studio photograph of that colour variant. Output at the original resolution, photorealistic.
