Personal Resource Bar: HP Color by % missing?

[Xancepants]

Hello all, I'm aware of a few addons that can achieve what I am looking for, such as KuiNamePlates, but I was wondering if any programming language guru(s) out there might know how to make a Macro / Script, or some LUA Code to make the Health on your Personal Resource Bar change color, based on % Value of missing HP? (That's the HP/MANA bar that appears directly below your character). For example:

100% = Green
75% = Green/Yellow
50% = Yellow
25% = Orange
>25% = Red



I found a similar script that does the same thing, but it's for Player Frame and Target Frame. Here is the code if it helps to give anybody an idea or starting point.


--[Color HP Bars Green at Full & Red at Low Health]
hooksecurefunc("HealthBar_OnValueChanged",function(self,value)
local min,max = self:GetMinMaxValues()
if not value or value<min or value>max then
return
end
-- change value to a percentage
value = (max-min)>0 and (value-min)/(max-min) or 0
-- recolor based on percentage
if value>0.5 then
self:SetStatusBarColor((1-value)*2,1,0)
else
self:SetStatusBarColor(1,value*2,0)
end
end)


Not sure if this is the correct place for this question and I apologize if it's not, but it seemed like the closest match! Any Help is greatly appreciated, and thank you in advance
