java中的颜色衰退

我最近已经完成了一个路径查找可视化工具的工作。我想知道是否有可能使用图形包的颜色开始为白色，然后淡入各自的颜色，如青色或黑色。现在我有它的颜色只是立即出现，并会认为它会看起来更好，如果颜色能够从彼此褪色。这是我到目前为止的代码和输出的图片

这里有一种方法。它使用计时器定期减少rgb颜色方案中的红色分量

import java.awt.event.ActionListener;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
import javax.swing.Timer;

public class ColorFadingDemo extends JPanel implements ActionListener {

    Color color = new Color(255,0,0);
    final static int height = 500;
    final static int width = 500;
    final static String title = "default title";

    JFrame frame = new JFrame(title);

    public static void main(String[] args) {
        SwingUtilities.invokeLater(
                () -> new ColorFadingDemo().start());
    }

    public void start() {
       Timer timer = new Timer(0, this);
       timer.setDelay(20);
       timer.start();
    }

    public void actionPerformed(ActionEvent ae) {
       int rgb = color.getRGB();
       rgb -= 0x10000;
       color = new Color(rgb);
       repaint();
    }
    public ColorFadingDemo() {
        frame.setDefaultCloseOperation(
                JFrame.EXIT_ON_CLOSE);
        frame.add(this);
        setPreferredSize(
                new Dimension(width, height));
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }


    public void paintComponent(Graphics g) {
        super.paintComponent(g);
        Graphics2D g2d = (Graphics2D) g.create();
        g2d.setRenderingHint(
                RenderingHints.KEY_ANTIALIASING,
                RenderingHints.VALUE_ANTIALIAS_ON);
        g2d.setColor(color);
        g2d.fillRect(100,100,300,300);
        g2d.dispose();

    }
}

简单：

int transparency=0；//透明度值；
int R=255，G=0，B=0//输入您的RGB值
颜色c；//然后可以在绘制方法中使用的颜色
线程t=新线程（）{
公开募捐{
而（透明度<255）{
int透明度=0；
c=新颜色（R、G、B、透明度）；//通过设置自定义颜色，可以定义R、G、B和透明度值
透明度++；
试一试{
int fadeTime=1000；//衰减过程应该持续多长时间
线程。睡眠（255/衰减时间）；
}捕获（例外e）{}
}
}
};
t、 start（）；//线程将继续在后台运行，直到透明度达到255
