Replacing variable value with variable name in scss with gulp?

Question

Layout

How can I automate the following process in .scss using gulp:

$white_color: #ffffff;
.foo {
    color: #ffffff;
}

so that the output automatically changes to

$white_color: #ffffff;
.foo {
    color: $white_color;
}

Those. all matches of the variable value were replaced with the variable name in the scss files. The plugin for VS Code does something similar, but it only works with colors, and, for example, it can no longer be applied to font variables:
