Okay, I understand the requirements. You want a Tampermonkey userscript that redirects Amazon product URLs to their most concise form, specifically https://www.amazon.es/dp/<product_id>, regardless of whether the original URL includes the product name or query parameters. Here's a robust solution, along with a detailed explanation:

// ==UserScript==
// @name         Amazon URL Cleaner (ES)
// @namespace    http://tampermonkey.net/
// @version      0.5
// @description  Redirects Amazon.es product URLs to the shortest /dp/ format.
// @author       You
// @match        https://www.amazon.es/*

Okay, let's break this down.

Yes, it is possible to achieve a color inversion effect in Ghostscript, similar to the invert(100%) part of your CSS filter. Replicating the hue-rotate(180deg) part exactly is significantly more complex within Ghostscript's standard processing model, but the simple inversion often gets you 90% of the way to a usable "dark mode".

The core idea is to use PostScript's transfer functions. These functions modify color component values just before they are rendered. To invert a color component c (where c is between 0 and 1), the function is simply 1 - c.

We need to apply this function to all relevant color spaces commonly found in PDFs: DeviceGray, DeviceRGB, and DeviceCMYK.

Here is the Ghostscript command you can use in a Bash shell script:
