dsh-theme-spectrum

DeepSeek Harness ships with only three visual modes — light, dark, and system-following — and the palette itself is essentially locked. If the default grey-and-white no longer suits your taste or your workflow, Spectrum is a standalone theme plugin built precisely to change that. It ships ten hand-tuned color presets, ranging from the neutral Graphite and the cool-blue Tide to the experimental Volt, each with both a light and a dark variable set. Combined with DSHs three display modes, that gives up to thirty effective appearances.

Spectrum follows a strict design rule: change colors, never structure. Layout, typography, spacing, border-radius, and animation are all left to DSH itself. The plugin swaps only color values — it does not scan the DOM, listen for mutations, or inject global !important declarations. That keeps its runtime cost negligible and avoids style collisions with other plugins. On uninstall, the bootstrap styles, theme overrides, settings row, and language dictionaries are fully removed, leaving no residue behind.

For extension-plugin authors, Spectrum exposes eighteen semantic CSS variables covering surfaces, borders, text, accents, focus rings, status colors, terminal backgrounds, and more. Plain DOM elements, portals mounted under body, and Shadow DOM content that actively consumes inherited variables will automatically follow the active preset regardless of plugin mount order. It also provides a small set of verified compatibility aliases for dshmarket and dsh-profile-plugin-manager, easing migration.

It is suited to any user who wants to give DeepSeek Harness a fresh complexion, and especially to authors building DSH extensions whose components need to track the global theme. There is no token editor, no per-workspace or per-session switching, and the preset list is fixed. If you want a minimal, zero-maintenance, set-and-forget recoloring solution, Spectrum hits the sweet spot.
