The color palette is inspired by the visual identity of Durham University; the package is an independent academic contribution and is not an official or endorsed institutional template. The package includes a demo presentation and full documentation. ---------------------------------------------------------------------- The package’s Catalogue entry can be viewed at https://ctan.org/pkg/beamertheme-durham The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/beamer-contrib/themes/beamert… ------------------------------------------------------------------------ Thanks for the upload.
