我正在学习Scala,我无法弄清楚如何在Scala中最好地表达这个简单的Java类:

public class Color {
  public static final Color BLACK = new Color(0, 0, 0);
  public static final Color WHITE = new Color(255, 255, 255);     
  public static final Color GREEN = new Color(0, 0, 255);

  private final int red;
  private final int blue;
  private final int green;

  public Color(int red, int blue, int green) {
    this.red = red;
    this.blue = blue;
    this.green = green;
  }

  // getters, et cetera
}

我最好的是以下内容:

class Color(val red: Int, val blue: Int, val green: …
