[FR]: Ability to change color of Systray Icon #1973

Brief description of the feature request

Hello. Old user of Quite RSS here. I made the jump a month ago and I'm happy with the result. Thank you for keeping this new project active.
I was used to the light green color of RSS, which stood out nicely on my taskbar. RSS Guard uses a dark orange color, which I find hard to see. Is there a way to choose the color used for notifications? The monochrome color is fine for when there are no notifications, but I have trouble seeing the orange as an alert. Thanks in advance.
