Axanthic is a colour mutation, not a pattern one, so the underlying pattern can vary considerably. Photos would help a bit, allowing for the fact that axanthics do not always photograph very well, but it is almost impossible to spot what type of axanthic you have visually, if that is what you have. Did you get any information from the person that you got these snakes from? Young axanthics tend to be black, grey, white and silver looking-the subtle brown shades only come in on older animals. I would think that it is unlikely that you would be given one without knowing what it is.
