Thanks for the reply as usual Phanx;

The oUF layout is my own, and I've not created ANY border for the auras, they inherently have a 1px by 1px border around them. As a reference, here is the code I use to produce my buffs and debuffs.

lib.generate_Buffs = function(f)
    b = CreateFrame("Frame", nil, f)
    b.size = 19
    b.num = 40
    b.spacing = 1
    b.onlyShowPlayer = false
    b:SetHeight((b.size+b.spacing)*4)
    b:SetWidth(f.width / 2)
    b:SetPoint("BOTTOMLEFT", f, "TOPLEFT", 0, 1)
    b.initialAnchor = "BOTTOMLEFT"
    b["growth-x"] = "RIGHT"
    b["growth-y"] = "UP"
    b.showType = true
        
    f.Buffs = b
end

There are no hooks or callbacks, so the border is definitely inherent; that being said, I want to set the vertex color of said border, but I am not sure how to reference it.
