Actually, thinking about it, the underlying representation doesn’t need to change, it’s just the point of Ustr creation that does. Seems like it ought to be possible to have a...
(If you’re ok with being limited to ascii that is)
FWIW from memory at Weta we had a control (on by default) that automatically compensated so the diffuse albedo remained the same at normal incidence.

Do you mean we're looping back around and actually "diffuse colour" was the best nomencalture after all? :P
agreed that albedo is a horrible term for this. I'm fine with reflectivity though personally as the referred- or integrated- nature being implicit in this context is ok imo. I...
ACES 2065-1 covers the entire spectral locus so you're not going to get negative RGB values there, but you _could_ get negative values if your colours are stored in a...
Leaving aside the colour space part of the question (see my reply on the metadata thread) for now, this is similar to the discussion we had on the UsdLux channel...
It's definitely defined, but it's defined to be dependent on the rendering space.
Yes, it's just (L,L,L) * RGB2
