ccc4是颜色RGBA格式， 0, 0, 255, 255是纯蓝

                                             255, 0, 0, 255 纯红

                                             0, 255, 0, 255 纯绿

渐变背景

blue = 	ccc4(255, 0, 0, 255)
		green = ccc4(0, 255, 0, 255)
		gradiant = CCLayerGradient:create(blue, green)
		
		layerFarm:setVisible(true)
		layerFarm:addChild(gradiant)
