How to tell if it's Pastel BEL

I'm currently hatching a clutch from Pastel lesser x Mojave. Got two BEL's... is there a way (other than breeding them) to tell if they are pastel BEL's? Appreciate any thoughts on this!

I'm in the same boat as you with one I hatched out a couple years ago....

As far as I have seen with mojave lesser being solid white only know by breeding it out like you said. Unless you use a super pastel lesser or mojave to create it.
