you can use script like:

private target: GradientRange = new GradientRange();
update() {
                this.target.color = new Color(r, g, b, 255);
                this.line.color = this.target;
}

or

update() {
                this.line.color.color = new Color(r, g, b, 255);
                this.line.updateColor();
}

to change line color
