Changing date picker row font color in android

Hi, I want to make my picker background color as white and the text color will be black. Below is my code -

var Picker = Ti.UI.createPicker({
        backgroundColor : '#FFF',
        color: '#000',
        type: Ti.UI.PICKER_TYPE_DATE,
        borderRadius : 5,
        width : Ti.UI.FILL,
        height : Ti.UI.FILL
    });

It seems, the backgroundColor is working but the color is not. i mean my picker background coloe is white and the text color is also white. so the text(picker date) is not focused and can;t be distinguish. how can i set my text color white ?
