Changing the color of a rectangle

[#1]

Hello

My question is acutally really simple: Is it possible to change the color of a rectangle using JavaScript/FormCalc?

It's just so easy to do this with buttons or TextFields but the .fillcolor command won't work with rectangles.

Rectangle1.value.rectangle.fill.color.value = "0,0,255";

Works fine, thank you.
