### Alternatives/Existing Solutions

I used this manual script to get the closet color matching my theme.

#!/usr/bin/env bash

# Full path to papirus-folders in case PATH is missing in post_hook
PAPIRUS_FOLDERS="/usr/bin/papirus-folders"

# Read hex from matugen output
hex=$(<"$HOME/.config/matugen/papirus-folders/folder-color.txt")
hex="${hex#\#}" # strip # if present

Start by reviewing the manual Bash script in the issue, including its Matugen color mapping, Papirus folder-color command, and icon-cache refresh. Identify the project entry point responsible for file-manager or icon-theme integration, then verify that actual file icons follow the Matugen color while folder icons continue to work.
