Is it possible to set a background color for main screen?
if yes how?

[hrbuckley]

Use one of the versions of the setBackground() method documented in the API for net.rim.device.api.ui.Field

you can change background color of mainscreen using following code:

this.getMainManager().setBackground(BackgroundFact ory.createLinearGradientBackground(Color.BLUE, Color.BLUEVIOLET, Color.BLUE, Color.BLUEVIOLET));
