Lunaria

Lunaria is a fam­ily of sooth­ing, moderate-​contrast color palettes for ter­mi­nals, text ed­i­tors, and tech­ni­cal doc­u­men­ta­tion. Lunaria's col­ors were gen­er­ated al­go­rith­mi­cally, em­ploy­ing the cut­ting edge of color sci­ence: the CAM16 color ap­pear­ance model and its as­so­ci­ated uni­form color space and chro­matic adap­ta­tion trans­form. Lunaria in­cludes three dis­tinct palettes:

• The Light palette is for users who pre­fer to read dark text on a light back­ground. It is de­signed to pro­vide the best fac­sim­ile of ink-​on-paper that an LCD mon­i­tor can pos­si­bly achieve. Its col­ors are op­ti­mized for view­ing in the bright window-​lit con­di­tions typ­i­cal of 21st cen­tury of­fice build­ings, but hold up well in a broad range of con­di­tions.

• The Dark palette is for users who pre­fer light text on a dark back­ground. Its neu­tral col­ors are de­signed to give an im­pres­sion of a moon­lit night and are de­rived from ac­tual spec­tral data col­lected from the Fred Lawrence Whip­ple moun­tain­top as­tro­nom­i­cal ob­ser­va­tory. It is op­ti­mized for night­time view­ing under dim, warm LED il­lu­mi­na­tion.

• The Eclipse palette is al­most iden­ti­cal to the Dark palette, but op­ti­mized for the same brighter view­ing con­di­tions as the Light palette is. The most vis­i­ble dif­fer­ence is that the back­ground is darker as a re­sult of com­pen­sat­ing for in­creased view­ing flare (am­bi­ent light re­flected off the mon­i­tor sur­face).

What's here

For a detailed, designer-focused introduction to Lunaria and how to use it in your own work, see https://lunaria.design. All other "official" Lunaria resources are here in this repo.

• The files lunaria-light.json, lunaria-dark.json, and lunaria-eclipse.json canonically define the respective color palettes.

• lunarize.py is a script for substituting color definitions (provided by one of the above JSON files) into a template.

• lunaria.ipynb is the Jupyter notebook which was used to generate Lunaria. Go here if you're interested in the gory mathematical details of how it was constructed.

• vscode/ contains the sources of the Semantic Lunaria extension for Visual Studio Code. (End-users are best off obtaining this through the Marketplace)

• xrdb/ contains X resource files for theming terminals such as xterm and rxvt.

• qterminal/ contains themes for QTerminal-based terminals such as Konsole and LXQt.

• gogh/ contains themes for terminals supported by Gogh, such as GNOME Terminal, XFCE4 Terminal, and iTerm.

• css/ contains CSS files for using Lunaria in web design.
