I hope you are well today and thank you for your question.

We can change its color by developing and using custom CSS code.

Could you please share me your site URL where it’s displaying and tell me how you want it to change so that I can help you to achieve it?

I visited your shared site but didn’t see any search form on it.

The URL that you have shard is for single attachement page URL and not search results page URL?

If you want to remove that information text from single attachement page then you can do so by adding the below CSS code in the Custom CSS option of Ivory Search plugin settings on the path Ivory Search -> Settings -> Settings

.single-attachment .post-meta-bottom,
.single-attachment .post-header {
    display: none;
}

If you want to remove the No comments text also then please also use the below custom CSS code.

.single-attachment p.nocomments {
    display: none;
}

Hi Lisa,

I hope you are well today and thank you for your question.

Could you please share me the page URL from your site where the search form is displaying so that I can test it?

Also would you mind if I log in to your site and do some troubleshooting? If this is ok then could you please share me your site log in details privately by checking the option “Set as private reply” when replying to this topic?
