How to change the colour of the search box magnifying glass section on splash page?

Hi all,

Is it possible to change the colour of the magnifying glass section within the search box on the splash page?

I have looked on other discussions and have seen it may be possible - however the method on how to do so has not been discussed.

Ideally, I would like to change the colour so that it is not transparent and stands out from the background colour.

Any ideas/discussion would be greatly appreciated! 😊
