A light and dark color theme derived from color science. Part of datum — see datum.w0zro.com.
Pick datum (dark) or datum (light) in Preferences → Color Theme.
Install
Search datum in the Extensions view, or:
code --install-extension w0zro.datum
It's on the VS Marketplace and Open VSX.
Notes
The theme JSON in themes/ is generated from the datum palette — don't edit it by
hand. The version in package.json is a placeholder: releases are driven by the
git tag, and CI packages the extension as ${TAG#v}. To build the extension locally instead of installing from a registry:
cd ports/vscode && npm i -g @vscode/vsce && vsce package
code --install-extension datum-*.vsix
