One way is: 

String rgb = "#0AF";
String rrggbb = "#";
for (int i = 1; i < rgb.length(); i++) {
    rrggbb += (rgb.charAt(i) + "" + rgb.charAt(i));
}

String hexColor = String.format("#%06X", (0xFFFFFF & intColor));

thats what i was searching. It will ensure that color string always will be #RRGGBB.

int newRgb = 17 * (((oldRgb & 0xF00) << 8) | ((oldRgb & 0xF0) << 4) | (oldRgb & 0xF));
