Yes, there is themes we can change in Figma setting:
Light/Dark themes
But it would be great to have another one called Black theme where it is true black not grayscale like Dark theme. I think it would be great for those whose use OLED display to design and it is just so much fun and looks cleaner with just #000000.
This is just the sample I use Ctrl + Alt + i to manually change the hex color of the Figma to #000000.
