Searching around I have found the technical explanation according to Kevin Vaughn with regards to sempervivum.


JungleShadows said: Yes the watermarks are from uneven distribution of surface waxes that causes the underlying anthocyanin colored cells beneath to have different shades. Think about adding candle wax over a basic clear color in different amounts and you have an idea as to how the colors can be affected. It adds a lot of distinction and beauty to those that exhibit these characteristics.

Kevin



I assumed that the uneven wax distribution would be cause by water and temperature (possibly light)
But now I am not sure if water is involved at all based on the explanation.
