java里颜色类默认的几种颜色对应的int值是多少？

public final static Color white = new Color(255, 255, 255);

public final static Color lightGray = new Color(192, 192, 192);

public final static Color gray = new Color(128, 128, 128);

public final static Color darkGray = new Color(64, 64, 64);

public final static Color black = new Color(0, 0, 0);

public final static Color red = new Color(255, 0, 0);

public final static Color pink = new Color(255, 175, 175);

public final static Color orange = new Color(255, 200, 0);

public final static Color yellow = new Color(255, 255, 0);

public final static Color green = new Color(0, 255, 0);

public final static Color magenta = new Color(255, 0, 255);

public final static Color cyan = new Color(0, 255, 255);

public final static Color blue = new Color(0, 0, 255);

其值在Color类内部以int的形式存着，24-32位为alpha值，16-23为red，8-15为green，0-7则是blue。默认的alpha值为全1，也就是255，完全不透明。

比如说

public final static Color pink = new Color(255, 175, 175);

表示在其内部颜色的值为255*2^24+255*2^16+175*2^8+175=4294946735
