Ok, Libraries it is then, thanks.
Libraries are a different beast, they're not really folders. There is an xml file that defines them. I'll look to see if there is a way to define color in the xml, or a way to get color changes to be applied to Libraries.
Now we're getting to the core issue.
I found another registry key that defines color
HKCU\Control Panel\Desktop\WindowMetrics
and modified rqColor.bat to query that key as well
you can run the query by hand
reg query "HKCU\Control Panel\Desktop\WindowMetrics" /s
or download and run the new rqColor.bat
Download
The download might be appended with a numeric - rqColor (1).bat - to avoid that, rename or delete the existing rqColor.bat file before downloading the new one.
the WindowsMetrics key might affect Libraries, I don't know. Post the results of the query (either a screen shot of the "by hand query" or a new HKCUcolor.txt file produced by the new rqColor.bat.
There's also another way to change colors through Windows Control Panel > Display > Change Colors
You have to start with a Basic or High Contrast > Windows Classic theme.
This method is preferred over registry editing for two reasons
1) You don't run the risk of corrupting the registry
2) You can preview the colors selected (albeit a small color box)
It will take some additional customization to set the desktop background image, sounds, screen saver, etc. - but that's why it's called customization :)
See: Window Color and Appearance - Change
Scroll down to OPTION TWO, step 7 describes color changes
The tutorial explicitly states that this will only work if you select the Windows Classic theme as the base.
Post any progress or questions. Thanks.
