Melakon... Bottom left hand corner of your screen.
There's a "style choser"
(Are there more choices for those with paid accounts?)
I think you're using Old Grey, which is default, which is like if they never switched to colour after the first 15 minutes of the Wizard of Oz.
Big Blue which is what I use, which is what the default used to be, or close to it when I started two presidencies ago.
Big Blue is much less Soviet than old Grey.
