我想使某些fish配色方案提供给运行Ubuntu的某台计算机的所有用户，因为系统上的一个用户报告说，默认的fish配色方案太暗，他们无法通过PuTTY查看，当从Windows框中SSHing到系统时。为 * 特定 * 用户设置配色方案需要将一系列通用变量保存到文件$HOME/.config/fish/fish_variables中。在配色方案的情况下，文件将包含行，如

SETUVAR fish_color_autosuggestion:707A8C
SETUVAR fish_color_cancel:\x2d\x2dreverse
SETUVAR fish_color_command:5CCFE6
SETUVAR fish_color_comment:5C6773

SETUVAR fish_color_cwd_root:red

我认为这同样适用于系统范围的fish设置，所以我将上述行保存到/etc/fish/fish_variables中，并以测试用户身份登录。但是，测试用户的配色方案未更新为上述配色方案。
我需要做什么来为Ubuntu上的fish shell的所有用户设置更亮的默认配色方案？

编辑

我确实想到，我可以通过使用set -x variable_name value简单地导出/etc/fish/config.fish中具有相同名称的 * 非通用 * 变量，但这似乎有点脏，我有点担心作用域规则可能会扰乱用户自己希望进行的任何设置。对此有何评论？
