No I want to save what HN is use and add it to something like TamperMonkey user scripts so I get the alternating colors for HN permanently. I tried before but I failed. Do you know of a solution?

Since it's not done via CSS here, I suggest not copying the existing approach directly but recreating the same effect using CSS only.

If you look in the DOM tree / source like I proposed, you see that the list is already a table, so you can use that exact approach you already mentioned.

    table tr:nth-child(odd) td.rank{
        color: red;
    }
    table tr:nth-child(even) td.rank{
        color: green;
    }
