Change color of html paragraph inside repeater

I design custom e-commerce product pages. Here I want to change the custom HTML paragraph color inside the repeater of additional information of the product. How will I do this?

export function additionalInfoSectionsRepeater_itemReady($item, itemData, index) {

const button = $item(‘#additionalInfoButton’);

const description = $item(‘#additionalInfoDescription’);

button.label = itemData.title;

description.html = itemData.description;

}

Here I want to change color (description.html) this paragraph. How will I do that.

Thanks
