A device includes a support including at least a first area and a second area, and a plurality of first light emitting devices located over the first area of the support, each first light emitting device containing a first growth template including a first nanostructure, and each first light emitting device has a first peak emission wavelength. The device also includes a plurality of second light emitting devices located over the second area of the support, each second light emitting device containing a second growth template including a second nanostructure, and each second light emitting device has a second peak emission wavelength different from the first peak emission wavelength. Each first growth template differs from each second growth template.
