What is tomorrow-theme?

Tomorrow Theme is a color scheme for code editors, released publicly on February 14, 2011. A color scheme sets the background color and assigns specific shades to different parts of your code: keywords, strings, comments, and other elements each get their own distinct color. The author had been adjusting a personal editor theme since 2005 before deciding to share it. The design intent is practical: make code easier to read by giving each element a color that adds meaning and helps you identify it quickly. The README describes the overall character of the theme as colourful but with muted colors and sensible syntax highlighting. This means the palette leans toward restrained, medium-saturation tones rather than highly saturated or garish ones, with the goal of being comfortable to look at for extended periods while still keeping code visually clear. The repository includes five named variants, each shown in the README as a screenshot of Ruby code alongside a palette swatch image. Tomorrow Night is a dark-background version. Tomorrow is the light background counterpart. Tomorrow Night Eighties uses a dark background with a warmer, softer tone. Tomorrow Night Blue applies a dark background with a blue tint. Tomorrow Night Bright is a dark scheme with more vibrant foreground colors for higher visual contrast. The README is otherwise very brief. It does not document which text editors or applications are supported, and it does not include installation instructions or setup steps. The five screenshot and palette pairs make up the bulk of the content. The repository is tagged as CSS.
