During the past few months, we have seen Windows 10 go from a simple user interface to one that has more customizable options such as being able to change the accent colors. One area Microsoft has yet to update is the title bars as they have been white during nearly the entire beta period. But thanks to a simple modification, if you want to change the colors, it's as simple as applying a new theme.
Here's how it works: download the zip file from the link below (no warranties on this, try at your own risk, we take no responsibility for anything that may go wrong here) and then extract the zip file. After extracting, copy the files to Windows -> Resources -> Themes so that it looks like the image below.
Once you have copied the files, double click the 'windows' file and this will apply the color to the title bars. If you want to change the color, simply go to the personalization menu and switch the accent color and this will change the title bars to whatever color you want.
Seeing how simple this modification is, we are surprised that Microsoft has not turned this feature on but there may be compatibility issues that are not obvious. For now, the company isn't commenting on if or when this functionality will arrive, but until then, you can use this modification to enable the feature.
