Mark Embling is an independent software publisher whose catalog, available through markembling.info, focuses on utilities for working with colour in design and development workflows. The publisher's range consists of two complementary products that approach colour management from different angles, serving both command-line enthusiasts and users who prefer graphical desktop applications. The first product, pal, is a command-line tool for working with colour palettes, aimed at developers, scripters, and power users who want to inspect, manipulate, or generate palette data directly from the terminal or integrate such operations into automated pipelines and build processes. The second product, Palette Picker, is a Windows desktop application for selecting and managing colours, providing a graphical interface suited to designers, front-end developers, and anyone who needs to choose, organize, and maintain sets of colours for user interfaces, websites, artwork, or branding projects. Together, these tools reflect a focused specialisation in colour-centric software: pal fits naturally into developer tooling environments where keyboard-driven, scriptable workflows are preferred, while Palette Picker addresses visual, point-and-click workflows on the Windows platform. Typical use cases include creating consistent colour schemes across projects, extracting or adjusting palette entries, previewing colour combinations, and keeping reusable colour collections close at hand during creative or technical work. Although the catalog is small, its tight thematic scope gives the publisher a clear identity: practical, purpose-built utilities that help users handle colour accurately and efficiently, whether at the command line or within a traditional desktop environment.
