Time is right
There are 2 different lines of vinicolors. The 'JAC' types are recessive when breeding, vinicolor in the homozygous, peacock flames in the heterzygous form. It may be a multiple gene trait, as the numbers from flasks don't quite line up with the theoretical 25:50:25. At least in my experience. The callosum 'JAC' petals have heavy spotting and a shape that might actually justify calling them a different species to the eye of some taxonomists. Don't know if this idea was ever accepted by Kew, but when you see a pure 'JAC' type that has no normal callosum in its background it looks pretty different.
The "Sparkling Burgundy" type callosums are much more callosum like in plant and flower shape. No doubt about whether or not they are callosum, they are true callosum. Usually few spots in the petals. Here the vinicolor trait is autosomal dominant. The homozygous and hetrozygous forms look about the same, full vinicolors. It may be a multigene trait too, as sometimes a touch of white on the dorsal, especially in the heterozygous forms.
When blended with JAC type, a whole range of colors is possible. Most complex vinicolor crosses today have genes from both lines.
Norito Hasegawa is the only person I know that has maintained pure lines of both types of callosum. Others may have too, but he is the only one I know of that has seedlings of the 'Jac' type that have not been outcrossed to normals.
