It is a gene that probably origins from muted japan blue. Below you may find photos for comparison.
This gene colours whole body for blue. In my opinion forebody is stronger colored – intensity of color in this part of body can be compared with japan blue. Peduncle however is less intensive. Possibly colors can be positively affected by further selection for more reflective guanine in peduncle and mixing with other known reticulata genes. I am looking forward what future brings with this new gene.
