I find the contrast to be perfectly fine. But someone with a different monitor can see completely different colours/contrast.
The only thing I can see is maybe slightly making it darker wouldn't hurt anything.
To the extent I still use Google (various products not just search) one thing is constantly happening is that setting options are removed. I find links showing me how to fix what Google has broken and then the settings I can use to do so have seemingly been completely removed by Google :-( This continuing practice has encouraged me to move more and more away from Google. DDG is my default, though still use Google search a fair amount when DDG doesn't give great results or I want to filter by date.
Which is why you chose to write your comment in a low contrast colour.
