Simply put, I believe that the way in which the terms "physical damage" and "magic damage" are currently being assigned the same colour as "AD" and "AP" respectively is detrimental in both clarity and purpose.
My arguments from the Discord channel:
"I'm simply proposing that by using the same colours for physical/magic damage as AD/AP, we're creating a link between them, and there is indeed a strong correlation between the two, but it's not absolute. The very example you're showing us while saying "still not seeing a problem" is an ability with hybrid scalings, which may confuse some people as to why magic damage is coloured as AP when there is clearly an AD ratio on it. Another example may be Corki's innate where his autos deal both physical/magic damage, but only scales on AD.
To make things clearer, I think we should, as said above, either rid of the whole idea of giving damage types except for true damage colours, or give them colours that aren't AD/AP."
"... it may lead to a general misconception that AD and AP are inherently linked to physical and magic damage respectively, which isn't true.
Seeing from how often I see snippets of the Wiki screenshot and used as visual info on some league vids, this should be avoided if possible."
For the reasons stated above, I propose that we either:
1) Remove the usage of {{as|}} on "Physical / Magic damage" (though not true damage, as it has its place as a unique damage type which can't be mitigated).
2) Assign new colours for "Physical / Magic damage". However, I do not know which new colours should be assigned, though as Tylobic said in the Discord channel, the in-game colour of light purple / purple could be used for magic damage. This option is burdened by the fact that the in-game colour for physical damage uses a near identical colour to health/attack speed on the Wiki.
Thank you for your time.
EDIT: Will be following up on the most popular choice soon, which most likely seems to be assigning new colours as of now.
