From Satori‘s description:

Satori is an elegant and clean color scheme for Vim. It looks great on black or white backgrounds.

So, let’s see white-on-black first with standard colors:

As you could see, it doesn’t have many colors, just three in this screenshot, white, red, and green. Now take a look at the Koehler color scheme that I actually use:

Clearly, it has many colors. As I switched back and forth between two screenshots, I begin to feel that there really is not much different between them. Because there is also font style to help distinguish some syntaxes. Visually, yes, they look totally different, but the differences might just be unnecessary, or simply for aesthetic reason.

And, lastly black-on-white:

This reminds me of something—the red text on white background—but I just couldn’t put my finger on it.

Anyway, Satori is a simple color scheme, less than 60 lines. It’s written by Rudá Moura, licensed under Charityware (GPL-compatible), same as Vim, the source code can be found on GitHub. It seems to have long history since the copyright years ranging from 2006 to 2014.
