Compositions and methods of producing colored paper products and agents for making such products are disclosed. Surface-modified pigments can be manufactured to provide selected coloring in a paper product. The pigment can include filler particles that are bound to one or more dye components with a coupling agent, such as a silane coupling agent or a polymer such as a polycation. The pigment can also be formulated to produce a paper product with better particulate and/or fines retention, and/or higher strength by including components that can interact favorably with the fibers of a paper material. The surface-modified pigments can also be utilized to make coloring formulations such as inks for printers and other applications.
