MacOS: QLineEdit focus highlight color is lighter in default Mac style, than in other apps in Mac

When using a default "macintosh" style in Qt application on Mac OS Mojave Light mode, QLineEdit focus highlight (blue border around the QLineEdit) is lighter than other line edits in Mac (non qt). I think the highlight color may have too much transparency / opacity as the border is darker than other line edits in Mac on dark mode.

I don't have an example app, but a simple app with QLineEdit should be enough to demonstrate this issue
