Workspace happy environment is a way to make the workspace more comfortable. It can be done in many ways:
Choose a theme
Using the theme of your choice. If you have installed a theme, it will change the color scheme and some other things that are related to making your workspace more comfortable. For example, if you install “Dark” or “Light” themes, then all of the colors will be changed to dark blue or light green respectively. This makes it easier for people with different color vision problems to work on their computers without having any problem identifying what they are doing at any time during working hours (even when they don't use the computer).
Use the right toolset
Changing keyboard shortcuts so that they fit with your needs better than before (for example, changing Ctrl+Tab shortcut from Tabbed browsing mode into something else like Ctrl+Shift+Tab). I have installed the “Dark” theme, and I can say that it is very comfortable to work on my computer.
Using a comfortable chair for working on computers. There are many different kinds of chairs that can be used to make the workspace more comfortable, but there are only two main types: office and home office chairs. Office chairs can be found in most offices, and they usually have wheels so that you don't need to worry about moving them around when you need to move from one place to another (for example, if your computer is in a different room than where you currently work). Home office chairs are also very common because most people like having their own space at home while they work on their computers. Both types of chairs will help make the workspace more comfortable by helping reduce back pain or other problems related with sitting too long on a chair without getting up once in awhile (which is not good for anyone's health). I personally use an office chair since it has wheels which makes it easier for me to move around my computer desk while I am working on it. This way I don't have any problem moving my computer desk from one place into another when needed. Also, this type of chair will help reduce back pain because we sit down all day long doing our jobs using our computers and sitting all day long without getting up once in awhile is not good for anyone's health.
Have enough light
Having enough light in the room where you work on computers at night when no one else is home (for example, having lights turned off during office hours). This way we can see everything clearly without any problems related with lighting conditions changing throughout our working hours.
