Weird, that worked for me. Have you also set the color and markersize at the beginning of the experiment? Here is a working version https://run.pavlovia.org/dvbridges/sliderunits/html/ . The code:

# Begin Experiment
col = new util.Color('green')
markerSize = 35;

# Each Frame
try {
    if (slider._markerColor.int !== col.int) {
        slider._markerColor = col;
        slider._marker.lineStyle(1, col.int, 1, 0.5);
        slider._marker.beginFill(col.int, 1);
        
        // Triangle Marker
        slider._marker.moveTo(0, 0);
        slider._marker.lineTo(markerSize, -markerSize);
        slider._marker.lineTo(-markerSize, -markerSize);
        slider._marker.endFill();
        
        // Circle marker
        // slider._marker.drawCircle(0, 0, 35/2);
        // slider._marker.endFill();
        slider._needUpdate = true;
        slider._updateIfNeeded();

     }
} catch (err) {}
