It is possible to darken the font in app Store Updates

This is just a minor thing but I am wondering if the font in Software Updates can be darkened. I am nearly blind and it is very difficult to see the font when Software Updatre is running or when it is done. I can see it by maginifiying the screen ro very large but hewn I can't see anything wlse until I reduce the maginfication to some extent.

Thanks
