Similarities
The emergence of new mutations in color canariculture always involves the same problem: its
differentiation from the currently recognized factors. There are two factors that could generate some
controversy from its pigmentary effect or its standardization.
Pastel
It is due to the standardization properly carried out on the brown pastel specimens specifically, those
that are desired with the presence of an oxidized brown melanic mantle. The dispersion of the matte
factor also generates the presence of a melanic mantle on the back of the specimens, however, the
phenotypic appearance is considerably different.
