Thanks for the photos Jay! I would be 99.9% certain they are homozygous stripes, but some pin-striped motleys are very good mimics. If their pattern wasn't so broken and vanishing, I might give that additional 0.1% of certainty to them.
The name "Pastel" usually refers to a ghost motley with nice peachy colors, but dilute could be in there as a het or even homozygous because many breeders didn't know they had the gene in their collection, falsely identifying them as ghosts. Freshly hatched dilute anery motleys and stripe are fairly easy to identify as they have an overall blue-gray coloration. It's more difficult to identify the dilute ghosts, a task that I have been unsuccessful at so far.
