Micro-structures and directional and multi-directional coatings for uniformly colored and directionally colored photovoltaic modules and roof tiles are described. The photovoltaic roof tiles (650) include a glass cover (652) with texture of a micro scale on a first side, and one or more layers (654, 656) of a transparent material adjoining the first side of the textured glass configured to reflect light of a color. A glass cover can have texture on a first side and a layer of sphere shaped metal nanoparticles (810) adjoining the first side of the textured glass cover. Directionally colored solar modules can include a textured glass cover with texture on a first side and a coating layer covering one or more facets (1106) of the texture on the first side of the glass cover. The coating layer may be deposited by coating the textured glass cover in one or more directions.
