Went from kobold brown to Deep wood green again.

I'm just gonna keep feeding it the appropriate light fruit until it raises the values enough to hit soot black. I think I got my values so low that each time I use a fruit it can only choose from the 3 dark colors at the bottom of the spectrum.
Well at least that's my theory.

Does anyone have advice for me on this?

Fed him one valfruit, with message, so we'll see this afternoon. Advice truly welcome.
