Mograph Color Shader falloff weirdness

[Doctor_Pizza]

In my project, a Shader effector with falloff is changing the color of clones from black to white. This is wired up to the Octane emission tab, so you can think of it turning on a series of lightbulbs in sequence.

If I use a preset Falloff Function like Linear or Inverse Square, it works as expected: Lights change from pure black to pure white. (see attached project)

But if I use a custom drawn Spline Falloff Function, the clones never start completely black. They always start as dark grey, which is unexpected behavior.

Any ideas what's going on and how to fix it so they start off completely black?

Hi Doctor,
I have slightly moved to the left the selected point of the custom curve and now the cubes are black when turned off, please try with the attached file:

Unbelievable! Thank you very much!

I can't believe the answer was such a tiny shift of spline points to the left !
