Problem: How to randomize color on object?

[private static final int COLOR_LIMIT = 255;

// Generator for random colors
private RandomIntGenerator colorGenerator = new RandomIntGenerator(0, COLOR_LIMIT);

private Color randomColor = new Color (colorGenerator, colorGenerator, colorGenerator);

public void begin() {

score = 0;
colorSwatch = new FramedRect (Swatch_Location, swatchWidth, swatchHeight,canvas);
colorSwatch.setColor (randomColor);]
