So sánh phối màu sản phẩm

Build a clean product colorway comparison chart for the item shown in the uploaded reference photo, or for the product described in the user request when no photo is provided. Repeat the identical product in a tidy grid — same angle, same scale, same soft even studio lighting — with each cell rendered in a different colorway so that color is the only variable. Under every variant place a small round color swatch and a short plain-language color name, and mark the strongest options with a subtle star or check plus one brief tip on when that colorway works best. Keep the layout visual-first: an airy white or light neutral background, evenly spaced cells, thin ruled dividers, and a compact caption row instead of paragraphs. Preserve the product's exact shape, proportions, and material details in every cell so hues and finishes read accurately across the grid. No watermark, no brand logos, no busy decoration.
