Make artificial true damage white.
Lethality is pretty good at the moment and is being built on lots of champs who don't generally use it, as a result have u considered making a small change to its clarity and when you have more lethality penetration then they have armour the text becomes white to indicate you are doing true dmg. I feel like this would be a good clarity thing and make you more aware of what the stats are doing. Or maybe for the sake of making sure people know what type of damage they are doing make it a seperate colour.
Edit: Added the bit regarding different colour.
