When the pellets are heated and compressed for injection into the mold. The base material and the dyestuff pellets melt and mix before being injected into the mold.
Polypropylene (PP) is

Despite their extreme diversity of appearances and sizes, injection molded parts all begin to exist in the same form. Small plastic pellets. The basic colors of these granules vary somewhat depending on the material, but all are on a monochromatic scale ranging from transparent and various shades of natural to black (see Figure 1). Transforming these small, dull granules into a rainbow of colors as they exit the molding press requires the addition of a colorant: a process that can be very simple or very complicated depending on the case. It will be more complex if you are very demanding about your color.
