I think you have to wait a while but it will be "akebono-ban", twilight variegation.
When you crossed different flower color Astrophytum, it will be happened with a high percentage.
asterias: yellow petals and orange throat
myriostigma: yellow petals
If you crossed above 2 species, seedlings show akebono-ban, quite many.
Asterias and coahuilense have same flower colors.
These crossings will make less number of akebono-ban seedlings.
The akebono-ban is caused by a hybridization problem.
I assume you do not know what species were crossed because you bought seeds from others.
