Hi,
v1.42 of NCrunch (released October last year), introduced a series of
global configuration options that allow you to change the colour of the NCrunch tool windows within Visual Studio. The release also included a number of changes to the icons and UI elements to make them visible on dark background colours. While NCrunch doesn't yet have full alignment with the new VS colour schemes, these options should allow you to configure NCrunch closely enough to avoid eye-blistering contrast between the background colours in VS.
Full alignment with VS colours will require a complete rebuild of the NCrunch UI (yep, it's not simple!), which unfortunately can only happen as part of a major revision of the software.
Cheers,
Remco
