+
+JonathanDarker is a color scheme inspired by
+[JetBrain's](https://www.jetbrains.com/)
+[Darcula](https://jetbrains.com/help/idea/configuring-colors-and-fonts.html).
+
+The scheme retains many of the same colors used in its ancestor's palette, and
+aims to compose a clean, peaceful, and professional visual.
+
+The palette consists of 16 colors, corresponding to the values used in
+[Xterm](https://en.wikipedia.org/wiki/Xterm)'s 16 color protocol.

+
+[`palette.sh`](./palette.sh) can be `source`'d to make the color palette
+available to other programs. The theme is best rendered as a light-on-dark
+theme, using Black as the background, Silver as the foreground, and Grey and
+White as accents. For a dark-on-light theme, a White background, Black
+foreground, and Grey and Silver accents works well.
