New visual design is incredibly depressing

I really, really am struggling with the new black and grey design. The overall feel is incredibly sad, depressing, and not to be dramatic, but it makes me want to walk away from my computer. I would love to be able to choose the background color or highlights. Maybe even just a simple toggle between this “color” or the previous tones. Everything looks the same. Nothing stands out. And I just want to go use another tool if this is what I will have to stare at day after day.
