I am trying to find an obsidian Theme that mimics Outlook Dark Grey. The reason being is that i have astigmatism and the only on screen color theme that works is this as it reduces hazing and is easy for me to read. I tried Ai but it just cant get it right and I'am too old to understand CSS. I would dearly love to be able to use this theme its perfect in my eyes, any hints?
