Is there a way to control the colorspace of the colors generated when using the melanin parameter in the Karma Hair shader?
https://www.sidefx.com/docs/houdini/nodes/vop/kma_hair.html [www.sidefx.com]

e.g.
If I'm lighting a scene with lighting/lookdev with sRGB primaries vs. lighting the same scene with lighting/lookdev with ACEScg primaries how would I control the Karma Hair shader melanin to compensate for the difference in primaries? Is there anything happening under the hood, maybe with OCIO that could be used to deal with this?

I put in an RFE asking for control over this, but haven't seen any movement. It's currently hardcoded to sRGB primaries.

Thanks for the info jsmack. Hopefully we get control for this soon.

ideally there would be a separate node that generate melanin color based on related attributes that can be plugged to anything, including hair shader, to avoid monolythic nodes with too many controls and also to allow inserting anything like color transform inbetween
since melanin based color can be useful for much more than just hair
