Could I mix my desired color with ColorPrep pre-coloring?Updated a month ago

In principle, you can mix all shades together. It is also possible to mix a dark shade with a warm shade, but the result will not be quite as dark as two colors that you have dyed one after the other. Likewise, the color mixture will be warmer, i.e., less ashy, because you have added golden or reddish color pigments.

Therefore, a particularly dark or cool color result can only be achieved in two steps.
