Accessibility colors - unwanted behaviour

[Redhpm]

Hi,

I changed the background colour of my pdf files as well as the text colour, and it was perfect until I noticed a problem.

On some parts of documents (I identified them as frames probably created with LaTeX), only the text colour changes and not the background colour. There's also the overline which isn't affected (cf picture). Is there a way to force these frames having the same colour as the rest of the document?
