I like to set the Windows Desktop to a specific color to easily identify it from other desktops I may have open. This way when I have multiple Remote Desktops running I can quickly see which one I need to click on. At a minimum I usually set the background color of the Desktop.
Recently though, I started making custom images that I use as wallpaper that incorporate color idea and adds information to positively identify the server I am working on. This information usually includes the host name, IP address, a brief description, and the type of OS running.
I try to make the color the same as the color associated with the primary software installed on the server. For example, our Prophet21 server is purple since that was their primary color in their logo, orange is used for our Shoretel server, etc. Some servers just have a color that was picked randomly years ago and stuck. Our database server uses olive while our webserver uses teal.
I use Gimp to make the images and put them on the root of the C: drive of the server. Since these are servers themes are usually disabled. To make the image appear as wallpaper I have to open them in Paint and from the File menu select “Set as Wallpaper”. The following are examples of wallpaper for a few of my servers.
This is a screenshot of my Taskbar showing how helpful these wallpapers are:
