Maybe you were looking for another Nord Beamer theme?

• https://github.com/junwei-wang/beamerthemeNord

By default, theme will be displayed using dark mode; however, this can easily be toggled to the light version of the theme by providing an option to the \usetheme{sthlmnord} command,

% > > > Choose Theme
\usetheme[mode=light]{sthlmnord}
%\usetheme{sthlmnord}

By default, source code printing is done using the listings package. The reason is that it will be easier to style the code using Overleaf.com in the future.

However, if you would like to use the minted package styled with nord, then just pass the codeminted option to the documentclass command. While minted should work out of the box, this theme includes the custom nord color palette https://github.com/sbrisard/nord_pygments, that needs to be installed (see github repository for instructions).

If you do not want to install the pygements nord color theme, you can choose one of the installed themes by changing the beamerthemesthlmnord.sty file

\RequirePackage{minted}
% > > > Nord style Requires custom install: https://github.com/sbrisard/nord_pygments
\usemintedstyle{nord}  <====== Change to a default style
