- Same as Color.fromRGBO, if parameter has value, lock that value
- BaseRandomColor.withAlpha(int a)
- Fixed alpha
- BaseRandomColor.withBlue(int b)
- Fixed blue
- BaseRandomColor.withGreen(int g)
- Fixed green
- BaseRandomColor.withOpacity(double opacity)
- Fixed opacity
- BaseRandomColor.withRed(int r)
- Fixed red
