Before April 2018, Windows 10 in all its releases automatically based on the desktop background you have on will choose a window color that will match your desktop background.
Till later updates after April 2018, I felt Customize App Borders and Shadows in Windows 10 was pretty cool.
But now you have an option to customize your border color for Windows that are opened. This may not directly add productivity value, but I think it is pretty cool.
To customize your windows 10 borders and shadows, this simple steps should walk you through the process.
Step-by-Step process to Customize App Borders and Shadows in Windows 10
Choosing a Border Color
To pick a custom color for your windows borders:
Step1:- Navigate to Start > Settings > Personalization > Colors.
An alternative to this is right clicking on any unoccupied space of your desktop and selecting the “Personalize” option, in the new window select the “Colors” option.
Step 2:- Once you perform the navigation, this opens the windows with a range of colors to select from.
Under the “Choose Your Color” section, you will have to deselect the “Automatically pick an accent color from my background” checkbox.
Browse through the available colors and select whichever you desire.
Step 3:- Another option will be to scroll down and click the custom color option and choose from a color gradient.
Step 4:- Next, you would want to apply an accent to your color. To do this scroll down to “Show accent color on the following surfaces”.
Here you will have to enable the option for “Title bars and window borders” or in some editions “Title bars”.
Disabling and Enabling Shadows in Windows 10
After picking Border colors, this might be just the next step in increasing the aesthetic value of your operating system.
By default, Windows 10 enables drop shadows for each window. Just in case this feature is turned off, you can re-enable it or disable it if it is already on.
This seems to be one instant difference in aesthetic value between Windows 8 and Windows 10. The former did not use shadows and had a flat look with colored window borders.
Disabling and Enabling Shadows option is available in the old Advanced System Settings window.
Open the search textbox in your taskbar, type “Advanced system settings” and hit enter to open this option.
Alternatively, open your control panel and System and Security > System > Advanced System Settings.
On the Advanced tab of the System Properties window, click the “Settings” button in the Performance section. This brings a window with a list of options.
Next, under the Visual Effects tab, select the “Custom” radio button.
Next, disable or enable the “Show shadows under windows” option, and then click the “OK” button.
That is all you will need to do. And you could return to change or update this option in the future.
