Heater Blower Duct Color? ‘77 C3.0

[77Targa0912]

Refreshing the heater blower ducting from the HE to the blower motor. What is correct for a ‘77 Brown, Tan, Black? Do PCA judges care if I was ever to go down that route?

Thanks!

What's the "HE?" For the blower motor in the engine bay, the large diameter plastic piece that always fractures at the accordion bends has always been black. At least the ones I've seen. The smaller, flexible, cardboardy hoses for the frunk blower and into the dash were either black or grey.

I mean the heater ducts that run from the heater exchanger to the y-pipe at the blower motor. The accordion pipe from the shroud to the blower housing is in great shape.
