Tag value color change

It’s me again!! :smiley:
I’d like to have color of a tag number change to red if that value is negative and green if the value is positive. would this be an expression thing or scripting?
something like

if({Root Container.KL.LED Display 1.value} >= 0
	brighter(green),
	brighter(red)
	)

is that a correct expression for color or is there something else i can use?

umm ok figured it out lol

if({Root Container.KL.LED Display 1.value} >= 0,
	toColor("green"),
	toColor("red")
	)
