Nebula colors

Meet the colors.

Every great theme starts with great colors.
Five are not enough. Seven are too many.
A family of six, beautiful colors was chosen
through a critical and structured process.

Have your eye candy. And see it, too.

All six colors were painstakingly tested for ergonomics,
legibility, and aesthetics on several monitor configurations,
including sRGB, Adobe RGB, miscalibrated, grayscale, HDR,
high-contrast, low-contrast, f.lux, and more.

Multichromatic. Monochromatic.

All colors were tested together a monochromatic
environment to ensure their contrast levels match so
no single color catches your eye more than the others do.


Get more done with Focus Mode.

Modals fly above your code. Inputs come to life when focused.
And with the all-new Focus Mode, elements gracefully fade into
the deep blue-gray background when you're not looking at them.


A theme that's just your type.

The human mind takes 13 milliseconds to recognize a letter.
Multiply that by millions of letters every day, and properly-set type
saves time, reduces eye strain, and can save you a few headaches.
Nebula recommends SF Mono for code. It's fantastic.

The little things.
