NetBeans中的Java Swing：JButton的背景色不变

我在macOS上的NetBeans中的Java Swing项目遇到了一个问题，特别是与组件的背景颜色有关的问题。我在GUI中有一个JButton，我试图从属性中设置它们的背景颜色。但是，尽管在代码中设置了颜色值，但当我运行程序时，背景颜色并不像预期的那样显示。
下面是initComponents方法的相关代码片段：

// Code from initComponents method
jButton1.setBackground(new java.awt.Color(102, 255, 51)); // Light green color
jButton1.setOpaque(true);

jLabel1.setBackground(new java.awt.Color(255, 51, 0)); // Bright red color

字符串
设置setOpaque（true）属性。已重新安装NetBeans。已尝试使用面板和不使用面板。尽管进行了这些努力，但背景颜色并未按预期更新。在macOS上的NetBeans中，特别是在M1芯片上，Java Swing是否存在任何已知问题？如果您有任何关于如何故障排除和解决此问题的建议，我们将不胜感激。
下面是整个代码：
