Color varieties are put into breeds every other day. As long as the breed fits the standard in all other aspects when the project is done it's that breed. If it looks like a duck and quacks like a duck then it's a duck. The photo in question doesn't show if the bird indeed has muffs and beard. Wouldn't even know about body type confirmation- not my breed, but if everything stacks up excepting color than it's simply a new color for breed. Take the unrecognized Wyandotte variety of blue laced red for example. They indeed look like Wyandotte in every way but that variety is not in the standard.
