1. A photovoltaic roof, comprising:
a first photovoltaic roof tile, comprising:
a first transparent front cover;
a first back cover;
a first plurality of photovoltaic structures positioned between the first transparent front cover and the first back cover, wherein a respective photovoltaic structure has a front surface facing the first transparent front cover and comprises one or more solar cells; and
a first colored layer extending across a surface of the first back cover, wherein the first colored layer is a first background color that matches a color of the front surfaces of the first plurality of photovoltaic structures; and
a second photovoltaic roof tile, comprising:
a second transparent front cover;
a second back cover;
a second plurality of photovoltaic structures positioned between the second transparent front cover and the second back cover, wherein a respective photovoltaic structure has a front surface facing the second transparent front cover and comprises one or more solar cells; and
a second colored layer extending across a surface of the second back cover, wherein the second colored layer is a second background color different from the first background color, the first and second background colors being selected to mitigate contrast within a respective photovoltaic roof tile, wherein the first background color contrasts more with colors of front surfaces of the second plurality of photovoltaic structures than with the colors of the front surfaces of the first plurality of photovoltaic structures.
