When working in AutoCAD the display of objects using color 7 (white) with a white background compared to when the background is black, a built in correction for display can be seen:
AutoCAD layer colors have an intuative display for objects that use the color 7 (white), unlike Map 3D when objects match the background color.
THE ISSUE:
When working in Map 3D Feature Data Objects (FDO) and the color 7 (white) is assigned while a BLACK background is set the look is as expected, similar to AutoCAD entities. 
When connected Feature Data Objects (FDO) use color 7 (white) and a WHITE background color is used, the automatically “flip” like AutoCAD does NOT happen. Map 3D FDO entities WILL disappear: 
If, a color that is close to BLACK is then used for the Map 3D objects on a WHITE background, line work can been seen again:
This then presents an issue for the MAP 3D FDO objects when a the background is set to BLACK - again the objects disappear. 
THE SOLUTION:
Adding an outline to the geometry or a ghost to text entities as in the opposite color, for example:
- LIght objects with Dark outlines
- Dark objects with Light outlines
With outlines created, FDO object on a WHITE background can look like this: 
With outlines created, FDO objects on a BLACK background can look like this: 
Simple style edit can help with the display of objects when Map 3D objects colors are close to the background color.
