Method

intRGBToColor(final float pRed, final float pGreen, final float pBlue)
RGB To Color 
return Color.rgb((int) (pRed * COLOR_FLOAT_TO_INT_FACTOR),
        (int) (pGreen * COLOR_FLOAT_TO_INT_FACTOR),

int[]getArgb(int color)
Gets an ARGB int array from a provided color 
final int a = (color >>> 24);
final int r = (color >> 16) & 0xFF;
final int g = (color >> 8) & 0xFF;
final int b = (color) & 0xFF;
return new int[] { ClippedColorPart(a), ClippedColorPart(r),
        ClippedColorPart(g), ClippedColorPart(b) };
intgetColorFromArgb(int[] argb)
Gets an int color from an int[4] containing argb values. 
if (argb.length != 4) {
    throw new IllegalArgumentException(
            "ARGB int array must have a length of 4.");
