Hi nameless, sorry no there is not any way to set a different color independently for a style's wire drawing versus it's shaded surface drawing.

It's just built in to the display system that if you have a style with a color of full black, that is taken to be a black wire color and a white shaded surface color.

But it is possible to modify a setting in moi.ini that will cause all curves to be drawn in one fixed color instead of in the style color though, that's under:

[View]
<....>
CurveColorMode=ByStyle
CurveFixedColor=0,0,0

CurveColorMode can be either ByStyle or FixedColor
