A method for continuous production of fully colored and non-colored fertilizer particles having a median size of about 1 to 6 mm, with a predefined ratio of the fully colored and non-colored fertilizer particles, starting from a stream A of non-colored fertilizer particles. The method includes continuously separating the stream A of non-colored fertilizer particles into a stream C of non-colored fertilizer particles and parallel streams B1, B2, . . . Bn of non-colored fertilizer particles in a predefined ratio, continuously coloring the non-colored particles from the parallel streams B1, B2, . . . Bn with a non-rub-off coloring agent, such that the particles become fully colored, continuously joining the parallel streams B1, B2, . . . Bn, including the fully colored fertilizer particles, with the stream C of non-colored fertilizer particles downstream, thereby obtaining the mixture of fully colored and non-colored fertilizer particles, and, optionally, processing the mixture of fully colored and non-colored fertilizer particles.
