propertygrid read-only name cell

I have user request to change the forground color of read-only name cell.
The current color used is too light and hard to read.
The read-only value cell is also light but easier to read than read-only name cell.

I have read that it uses the themes:PropertyGridCommonDictionary.ForegroundDisabledBrushKey
which is set to SystemColors.GrayTextBrushKey.

I still dont understand how to override the default value.
and would appreciate an example of how to set the name-cell to use the normal forground color.


Thanks in advance.
