Disable Dynamic Windows 8.1 Tile Colors
Is there a registry setting to turn the dynamic tile color off?
Solution 1:
Short answer: No you can't turn off dynamic tile colours.
But you can create custom tile settings for each exe. Microsft describes this in How to customize Start screen tiles for desktop apps
You basically create a "exefilename".VisualElementsManifest.xml with the following contents:
<Application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<VisualElements
BackgroundColor="#606060"
ShowNameOnSquare150x150Logo="on"
ForegroundText="light" />
</Application>
If you choose a bright backgroundcolour, change "light" to "dark"
To activate any changes you make, you have to "edit" (basically update the timestamp) of the .lnk file in the startmenu.
