I realize now that the Find Search refers to a single text file and that the bright yellow search result color is related to PROJECT SEARCH. But I cannot find a way to change the highlight color of a Project Search result.
I could not duplicate your problem of the search results/binder colors. Are you using Scrivener V3? The Project Search highlight color is controlled here:

As the yellow default highlight color is disfunctional in a dark theme (yellow highlight over white text) I am looking for this exact information. Unfortunately, the posted screenshot is missing/not visible. Could you please briefly describe the location in text?
The Project Search highlight color is set under File/Options/Appearance/Textual Marks/Colors/Search Results Highlight.
