Questions Regarding Ensuring Helm And Spaceline Themes Match The Current Theme

[Samuel Banya]

Hey there,

So, I use both Helm and spaceline packages for my Emacs config.

However, whenever I change my theme, I often get weird results for both.

I believe the issue is that not all themes support Helm, and I don't think 
there's a way to truly customize the spaceline theme.

My main issue is that the spaceline looks mostly wonky since the colors of the 
separator arrows are completely off-looking, and Helm theme rarely applies to 
old themes (which is sad since I really want the Word Perfect theme to be 
universal in my case).

Is there any way to force this behavior, or do I have to figure out how to 
create corresponding themes? If so, is there an easier package to do this kind 
of thing?

The only theme that 'almost' works is Gruvbox, but even then, the Spaceline 
looks completely off.

*Here are my related Emacs config sections from my literate config:*
*** Add '~/.emacs.d/themes/replace-colorthemes/' to load path to add additional 
themes from 'replace-colorthemes' GitHub repo
#+begin_src emacs-lisp
  ;; Added this to add the 'replace-colorthemes' themes from GitHub:
