Help with targeting specific columns for changing the color of some words

Hey

So pretty confusing subject but what I’m currently doing is changing the color of specific words in my sections. So far I havent had any issues until I came upon sections that have columns.

Now my problem is, I don’t know how to target those columns individually so I can change the color of a few words inside.

This is the code im using for 3 sections so far:

setInterval(() => {
    changeColor();
}, 10);

function changeColor() {
    let paragraph1 = document.querySelector("#shopify-section-484ac221-7750-481b-8ad9-9a3557414814 .container .sixteen.columns.text-column");
    let paragraph2 = document.querySelector("#shopify-section-66f0799f-7a42-4714-84ff-d2b2d04e948c > div > div > div > div.rich-text__text.featured_text");
    let paragraph3 = document.querySelector("#shopify-section-cf0f65f3-1b9f-46ac-9b2d-664c0126b416 .psb-partner-heading .psb-utilities-heading__subheading p");

    if (!paragraph1 || !paragraph2 || !paragraph3) return;

    if (window.innerWidth < 756) {
        paragraph1.innerHTML = 
        paragraph2.innerHTML = 
        paragraph3.innerHTML = 
    } else {
        paragraph1.innerHTML = 
        paragraph2.innerHTML = 
        paragraph3.innerHTML = 
    }

All these 3 sections work perfectly. Of course none of these 3 sections have any columns, which is why it works without any problems for me.

Here is the screenshot of which section I want to target

If anyone can help, i’d greatly appreciate it! I’m only using this specific code for mobile as its optimized for that.
