[Trivial] Stealth icon is very similar to Telegram icon

I casually put the Stealth and Telegram apps icons side-by-side in the launcher and, maybe because I'm colorblind, sometimes I open Stealth instead of Telegram and vice versa, because I confuse them. I can suggest to change the background color of the icon to a completely different one, like red or green. Or move the orientation of the arrow from North-East to another direction.
