3D printing causes dark colors to look muted and gray. The darker the color, the more gray it may appear. It's particularly noticeable on black and dark brown hair.
Any display figures that you may have seen at an event are production samples and show how these dark colors may appear on your figure. However, it's important to note that each batch of figures will have slight differences from other batches due to the nature of color printing.
If you want to avoid this issue for your figure, we recommend choosing a lighter hair color or a hat option to minimize the amount of dark hair color that is printed and seen.
