To give you a little more space and/or time, or at least help you feel like you have them.
nothing to see here
nothing to hear here
take this time
take your time
open for you
here you are
when you need a quiet space
A soothing gray web page to open in front of other windows in order to create a quiet screen space that you can then re-size or -shape as needed, temporarily shutting out visual distractions and viewing just the things (if any) that you need or want in the moment.
when you want a dark space
A darker gray that I like as a background for images and videos.
when you want more color
A cheerful page; if you like, you can set it to loop and/or fill your screen(s).
when you want pure blackness
2021 will probably be shades of gray, but this and the when you want more light (below) may sometimes be what you want.
when you need more light
You can also use this when you just need more light on your IRL desk.
