Stuf perchp lua help

[Ashram35]

I found a post similar to what i need help with but it was a little older and wasn't 100% what i wanted. Mainly I'm looking to have the text for perchp be colored depending on what it's at. This is what I found code wise:

function(unit, cache, textframe)
if UnitExists(unit) then
local perchp = 100 * UnitHealth(unit)/UnitHealthMax(unit)
return "%.1f%%",perchp
else
local perchp = 100 * UnitHealth("player")/UnitHealthMax("player")
return "%.1f%%",perchp
end
end

Now i don't need the % sign or the decimals and i can remove that just fine but I'm not sure how to add the color to the text part. Any help would be greatly appreciated.

Don't worry about it i'm just an idiot and missed the hpthreashold colortag. Sorry about wasting a forum post on this.
