1. A bladder comprising:
a top wall and a bottom wall opposite the top wall; and one or more sidewalls extending between the top wall and the bottom wall of the bladder, wherein the top wall, the bottom wall, and the one or more sidewalls collectively define an interior region of the bladder, and wherein the one or more sidewalls each comprise an interior-facing side and an exterior-facing side; and
a multi-layer optical film operably disposed on the interior-facing side or exterior-facing side of at least one of the one or more sidewalls to impart a structural color having at least one hue to the one or more sidewalls;
wherein the multi-layer optical film comprises at least two adjacent layers having different refractive indices and at least one of the layers has a thickness that is about one-fourth of the wavelength of the visible light to be reflected by the multi-layer optical film to produce the structural color.
