Maybe. The LED colors on each Christmas wireframe display are carefully chosen to bring the character or scene to life. The M5 or M8 mini LED lights come pre-attached from the factory with the colors as shown in the product image. Christmas light displays that feature "sealed M8 LEDs" are molded at the factory for superior weather resistance and are not replaceable after production.
However, displays that feature removable/replaceable M5 bulbs (currently only Brite Ideas brand displays) can technically have their colors swapped. It is a labor-intensive process, though, as the caps and the bulbs need to be individually removed and replaced. If enough replacement caps and LEDs are available, the swap can be done for an additional fee. Contact us to inquire about this.
Any C7 displays feature standard screw-base bulbs, and they are quite easy to replace. If you want to mix-and-match colors, C7 displays may be a great option for you.
