If Corona have a hair shader that supports this data, the shader should have an attribute to addd stray colors to hair strands. This is the case with Arnold, Redshift, Renderman and VRay
So we would need a "stray hair" or "outlier hair" attribute in the hair shader? Do I understand this correctly?
Do you know how this is done in Arnold/Redshift/Renderman? (what is the name of the attribute and where to find it in the ui?)
