Change visual studio caret color

Just change the Text Select of the mouse to 'Windows Black'

I could not see the blinking cursor due to a black background as well. The fix in Visual Studio 2017 was to set the Item forground and background colors different.

Tools > Options > Environment > Fonts and Colors > Show settings for: Text Editor > Display items: Plain Text

It seems the cursor color takes its cue from Item foreground.

In Windows 7 I resolved this by modifying my Windows system settings to use the Windows Black (system scheme). The caret I-Beam shape is surrounded by a white stroke that stands out over dark backgrounds and invisible over pure white backgrounds.

Go to Control Panel-->Appearance-->Ease of Access-->Make the mouse easier to use

and choose "Regular Black"

You would think that that the Inverted option would work, but the color remains black over the dark greys of the VS 2012 dark theme. The Regular Black does work well though.
