You can add that into the prompt given to the AI already. E.g. a red truck or woman in a yellow dress. Although, I have found you need to find a name for the colour that represents it pretty accurately, otherwise it might add a tint to the entire photo. You might get poor results just saying brown or red instead of burnt sienna or something more specific.
