How to change pet bar hotkey color?

[atshn]

I'm using this code to change the color of hotkeys for all my bars. Works fine for everything except the pet bar. Is "PetActionButton" not the correct name or am I completely off and the code doesn't work for the pet bar at all?

for i = 1, NUM_ACTIONBAR_BUTTONS do
   local hotkey = _G["PetActionButton"..i.."HotKey"]
   hotkey:SetFont("Fonts\\FRIZQT__.ttf", 12, "THICKOUTLINE")
end

local function CustomizeHotkey(self)
   local hotkey = _G[self:GetName().."HotKey"]
   hotkey:SetTextColor(1, 1, 1, 1)
end

hooksecurefunc("ActionButton_Update", CustomizeHotkey)
hooksecurefunc("ActionButton_OnUpdate", CustomizeHotkey)
