Lindsey, your blooms are peloric this time as well. The darker color is probably the result of more light when they were developing. I have found some of my Onc. Alliance develop a deeper color when exposed to more light. Where all of the blooms have opened peloric on the two bloomings you have seen it will probably remain peloric.
Here is a link that explains Peloria in orchids.
