Answer

I don't believe what you are asking can be done but an alternative solution is this:

1. Convert your raster data to points


2. Create a unique ID field and populate it with unique numbers


3. Convert your point dataset back to a raster using the unique ID as the value field



4. Convert this raster into a polygon vector dataset, as each cell in the raster has a unique value then the conversion from raster to vector will not cause the grouping of cells.


5. Display vector dataset over your original raster in what ever colour you desire.

I don't use QGIS but in ArcGIS there is a fishnet tool that could simplify the creation of the vector grid, so probably worth searching for such a tool in QGIS first?
