The pink stars that were circulating shortly ago were 200mg MDMA, but as AMTDan said, some batches may not be up to par.
They're very speckled - and if I'm not mistaken is there some blue at the bottom of the pill on the left?
The ones that were going around and were legit 200mg MDMA - they were pretty uniform in color (per pill - the whole batch varied in colors, so I'm not surprised one of yours is a bit more orange and the other is a bit more pink; it's the fact that when i look at your pic up close, you can see lots of different speckles of color in each pill, that's all).
As was also said by people before me, you can't really tell without a test kit. I'm sure you could produce identically looking pills of different content completely.
