Problem:
How to show a term meta field when listing posts.
Solution:
Term custom fields can only be shown when querying terms. When displaying posts which have taxonomy terms assigned, to output term fields for the taxonomy terms it is necessary to create a taxonomy View to list the terms belonging to the current post (that condition specified as a Query Filter) and then to output the term field in the Loop Output section of that View.
It may make sense to use the option to display the View without any wrapper div (and possibly to remove unnecessary whitespace from the Loop Output).

The custom taxonomy shortcode context is the archive page itself, i.e. the term is determined by the URL (if it exists).
You want to output the term field for individual posts (and the term field belongs to terms, not posts).
To output the term field for a post you need to create another View—a taxonomy View which lists the terms for the current post and which outputs the term field for the term—and insert this View nested inside your first View where you want to output the term field.
Don't forget to set the option in the taxonomy View to output it without any wrapper div.
I edited your View and I removed all the whitespace from the Loop Editor, and I also removed the wpv-filter-meta-html shortcode from the Output Editor (because this View doesn't include any filter controls) and the View itself seems to be outputting just the colour hex code.
