I need help changing an individual collage image box to a different colour.
It would be great if the first box could be the dark yellow colour in our logo HEX#FDB515. Ideally I would like this to be done by adding a code box to the page, but I have not had any luck trying to do so.
I do not have any background in coding, although I've done a few smaller things with it from following tutorials and help online. So I'm completely lost at this point.
Can anyone suggest a code to use that could make this possible?
