The invention relates to a preparation device of colored glass ceramics. The preparation device comprises a glass melting furnace, a feeding channel, calendaring rollers, an annealing furnace and a crystallizing furnace which are sequentially connected, wherein the feeding channel is internally provided with a homogenizing tank, a transition feeding channel and a clarifying tank which are sequentially connected, a pigment can is arranged above the homogenizing tank. The invention also relates to a process for preparing the colored glass ceramics by the device. By the preparation device, color can be convenient to change, the transition waste plates generated by the change of the color is less, the waste is decreased and meanwhile, products of which the surfaces are provided with decorative patterns can also be produced.
