How to set Isocurves to 50% of object's color in display mode?

I swear I saw a screenshot of someone having this but I can’t find the setting.

Surface Edge has a setting for color reduction % but Surface Isocurve does not.

Hello- as far as I can see that is correct - no special setting on isos.


I think I may have asked for that a long time ago…

Well, I’d like to rephrase that from “special setting” to “cohesive/corresponding setting”… :wink:
