The issued patent indicates:
The patent or application file contains at least one drawing executed in color. Copies of this patent or patent application publication with color drawing(s) will be provided by the Office upon request and payment of the necessary fee.
The color image available through the USPTO is shown below. The design includes an interplay of color gradients and lightly rendered flowing elements that transition smoothly from one to the next.

While the USPTO publishes color drawings in greyscale, it also makes the color drawings available to the public as part of the official record. The scope of protection is formed by the color figures despite the patent copy containing only greyscale images.
OHIM, the agency responsible for designs in the European Union, publishes issued designs in color both through its website and on certificates. Hopefully, the USPTO will have the capability of printing designs in color in the future.
