What is the easiest way to configure the above in beamer? I have no
idea what the final structure of slide components would look like but
have info only that it's got to be black background, slide titles and
subtitles are to be in yellow and running text of various sizes are to
be in white.

I have been using
\usepackage{beamerthemeWarsaw}
\setbeameroption{show notes on second screen=right} % Both
\useoutertheme[subsection=false]{smoothbars}
\setbeamercolor{title in head/foot}{fg=Green}

which gives blue on white. How do I tweak this for the above colours
please?

It sounds as if a simplified version of this theme
https://topanswers.xyz/tex?q=1280 would be close to what you are looking
for:

\documentclass{beamer}

\setbeamercolor{background canvas}{bg=black}
\setbeamercolor{structure}{fg=yellow}
\setbeamercolor{normal text}{fg=white}

\begin{document}
\begin{frame}
\frametitle{title}
\framesubtitle{title}
abc
\end{frame}
\end{document}

While I haven't fully tested it out with my theme, this is pretty much
the colour scheme that I was looking for. Thanks for the minimal
example code.

How do I change the line under the frametitle to a different colour.
Using Warsaw theme it stays white irrespective of what frame element
colour I change

\setbeamertemplate{navigation symbols}{}
\setbeamercolor{background canvas}{bg=black}
\setbeamercolor{background}{bg=black}
\setbeamercolor{title}{parent=structure,fg=white,bg=yellow}
\setbeamercolor{titlelike}{parent=structure,fg=white,bg=yellow}
\setbeamercolor{structure}{fg=white,bg=black}
\setbeamercolor{frametitle}{fg=white,bg=black}
\setbeamercolor{headline}{fg=yellow,bg=yellow}
\setbeamercolor{upper separation line head}{fg=yellow}
\setbeamercolor{separation line}{fg=yellow}
\setbeamercolor{fine separation line}{fg=yellow}

Can you make a compilable MWE to recreate your mysterious white line?

Strange, I lost the white line below the frametitle with this change.
Did you get the yellow line after compilation or you're suggesting
this correction?

I'm suggesting this as a fix. That's not a line, but an artefact of a
shadow which did not adapt well to the background colour.

In this branch you can find a beamer version which uses a transparent
shadow and thus will automatically adapt to the current background:

Thanks for the code. I'll try this out.

I did a search for hrule in SO and got this link

https://tex.stackexchange.com/questions/343517/beamer-full-width-hrule-below-frame-title#343520

I added a \color to the \rule. This comes out OK, if I remove/drop
smoothbars though.

\setbeamertemplate{frametitle}{%
\usebeamerfont{frametitle}\insertframetitle%
\vphantom{g}% To avoid fluctuations per frame
%\hrule% Uncomment to see desired effect, without a full-width hrule
\par% <-- added
\hspace*{-\dimexpr0.5\paperwidth-0.5\textwidth}% <-- calculation of left margin width
\color{yellow}{\rule[0.5\baselineskip]{\paperwidth}{0.4pt}}%
} %\useoutertheme[subsection=false]{smoothbars}
