A while back I posted about the GUI version (<a href="https://news.ycombinator.com/item?id=15087244" rel="nofollow">https://news.ycombinator.com/item?id=15087244</a>) but I’m realizing the CLI tool is probably more appropriate for the HN crowd.<p>Themer is a set of npm packages that allow for generating custom, matching themes for many of your development tools (editors, terminal emulators, desktop/device wallpaper, Slack sidebar, Chrome theme, Alfred, etc.). A custom color palette can be used, or there are a number of pre-built palettes to choose from.
