I would like to make certain fish color scheme available to all users of a certain computer running Ubuntu, as a user on the system reported that the default fish color scheme is too dark for them to view over PuTTY, when SSHing into the system from a Windows box. Setting a color scheme for a specific user involves saving a bunch of universal variables into the file $HOME/.config/fish/fish_variables. In the case of a color scheme, the file would contain lines such as
SETUVAR fish_color_autosuggestion:707A8C

I figured that the same would apply for system-wide fish settings, so I saved the above lines into /etc/fish/fish_variables, and logged in as a test user. However, the color scheme of the test user was not updated to the above one.
What would I need to do to set a brighter default color scheme for all users of fish shell on Ubuntu?
It did occur to me that I could simply export non-universal variables with the same names in /etc/fish/config.fish by using set -x variable_name value, but that seems a bit dirty, and I'm a bit concerned the scoping rules might mess with any settings a user might themselves wish to make. Comments on this?

There is no /etc/fish/fish_variables, fish only reads the universal variables from the user's directory.

You can put the variables into /etc/fish/config.fish (or a file in /etc/fish/conf.d as long as it ends in ".fish"), but exporting them isn't necessary.
You would want to make them global - set -g, not set -x.
Of course this means a user would also have to use global variables.
An alternative is that you set the variables only if they haven't been set yet:
set -q fish_color_comment
or set -g fish_color_comment 5C6773
