Fill Color as a custom property on a template

Using Ignition 7.6.3 on Win7-64. Still new at this.

I’ve created two custom templates using linear scale components and level indicator components. I want to know how to specify the fill color of the level indicator component as a custom property. I have already created custom properties for scale min/max and tic mark spans, but now I want to specify the fill color of the level indicator components. For example, on one template I need the fill to be 255,0,0 (red) and on another I need to use 0,0,255 (blue). How do I specify the fill color, is it a string, three integers, or something else?

Got it.
I did not realize that there was a color data type - stumbled upon it and made a property of type color and bound it to the fill color.
