Este es el codigo de mi ventana principal, pero el problema es que no coje el color azul en este caso ni ningun otro, y me gustarias saber como puedo ponerle un color de fondo.

HOLA:

Bueno te recomiendo que en vez de heredar de la clase JComponent heredes de la clase Panel,, de esta manera creas tu panel principal.

this.setLayout(new Layout a Usar());

y le agregues el color:

this.setBackground(new Color(160, 160 , 220));

Ahora si agregas otro Jpanel dentro de tu panel principal

JPanel panel = new JPanel();

add(panel);

entonces tienes que ver en que posición queda para cambiar el color a ese panel y que no te cubra el área de fondo.

panel.setBackground(new Color(160, 160 , 220));

Espero te sirva.

Saludos y Suerte
