How might you change the limit to something other than NoL .5?

Also, how would you go about changing the hue of the shaded area?

is simple, giving B of the if function a value other than 0.
In addition, if you want a soft transition, you can also set the normal as follows:

Normal = VertexNormal + NoL * _softScale * LightVec;

Set the shading model to two sided foilage, and then you can control the shadow color separately by subsurface color.
The effect is limited, but it does work.
