All product photos are taken by professional photographers and have been carefully retouched and color-adjusted in post-production to keep them as consistent as possible with the actual products. However, due to differences in lighting, display color, and personal understanding of colors, there may be color differences between the actual products and the photos. The final color should be based on the actual product.
