Improve Subtle Contrast (or Colors) of Highlighting of Selected Tasks (so no squinting required)

On the windows app, when you select tasks, especially with CTRL+click or CTRL+A, I can never really tell whether it and what I selected because it goes from white with a hint of blue-ish to white. It is inconvenient and problematic to such a degree that I have actually spent whole minutes writing this feedback. I am sure this is so it can be pretty without a high contrast, but could we increase the contrast in a manner so at least I can tell it has been selected? Especially since in the windows app, actions often do not "take" on the first click.
