Hi George,
From the look of the pictures, it looks to be a bit of heat damage to the pigment in the thicker sections. A way round it would be to cool the mould a bit before you pour the resin so it has a bit of capacity to absorb more heat and knock some of the temperature out of the exotherm. This might slow down the cure a bit but if it saves the pigment then it might be worth it.
