Part wireframe color in assemblies

I know that if I check "Apply same color to wireframe, HLRand shaded" under the document properties colors for my parts, thatwhen I switch to wireframe, the lines will be the same color as theshaded part.

I have an assembly, that contains several parts that do not havethat check box checked. It also contains several that do. When Iswitch to wireframe, some of the parts that should have their linescolored, are still black lines. If I open the part and view it inwireframe, the lines are colored not black. Any clues why it mightbe doing this?

I did try making sure that the part did not have a color set at theassembly level.
