Perhaps the Circle doesn't know the 'g' value has changed?  Maybe try CircleShape.fill = new Color(255,colourvalue,0) and see if that works?

Hello, I am confused on why my screen is not re rendering. 

My code looks like . 
const colourval = new Color( 255, 0, 0 );

const CircleShape = new Circle( 50, { fill: colourval } );

model.sliderProperty.link( colourvalue => {
colourval.g = colourvalue ;
} );
this.addChild( CircleShape );

My model.sliderProperty colour value goes from 0-255, and the colourval changes when I move my slider across from one side to the other, similar to the estimation simulation. However, when I move my slider, the CircleShape colour fill does not change, and I am confused as to why. 

Any sort of help is appreciated, thank you.
