Nice!
I have Sharry Baby 'Sweet Fragrance' which typically has the whitish lip with the purple spot in the center, but when buds develop in cool temps, the whole flower is purple - of course, that doesn't mean that's what's going on with yours, but putting it out there as a possibility - it's certainly possible there's a cultivar that always blooms solid colored
*photos attached of my Sharry Baby blooms from late 2012 - one spike developed over summer, the other during fall*(grows outdoors, so definitely lower temps during the second spikes developement)
