First two photos show early opened flower with yellow lip; third one shows matured bloom with blushed lip.
This is a Tom Perlite (San Francisco, Golden Gate orchids, who only keeps a handful of Onc alliance plants now) cross, purchased from Cal-Orchid in Santa Barbara this fall.
It had no roots when I bought it! And may very well not have them now. But about a month after I got it it started pushing out this spike. It's quite large and with all that energy stored in the bulbs, I think it will root just fine once it's done with this spike (which is just about kaput now).
