At least be very careful and pry the seed shell off and see what’s underneath. Maybe that colour orange back is purple. Maybe it’s green. Play with it a little. Let us know.
Ain’t dead till it’s DEAD. Ive had purple seedlings like that before. Soak the shell for a couple days and try to take it off with tweezers. If it’s worth planting, it’s worth trying to save. It hasn’t damped off or rotted yet.
