# Theme format riso reads and writes a theme format that originated in [Omarchy](https://github.com/basecamp/omarchy): the `colors.toml` palette with its semantic key names, the template dialect, and the rule that files a theme ships take precedence over generated ones. Implementing it rather than inventing another one is a deliberate choice. A theme is work, and two incompatible formats would only mean that work gets done twice. Credit for the design goes to that project and its contributors; Omarchy is MIT licensed. riso's implementation is its own, and so is where it goes from here.
