Had a question on breaded coconut shrimp turning black or green

I found green stuff in my tempura when I took a bite and instantly threw it away.

I hope you didn't eat it!
Any food that turns black or green should be disposed of pronto. Never a good sign!
I can't think of any breaded food that benefits from being refrigerated overnight prior to cooking.

Don’t eat it and throw away!

This is the kind of dish that needs to be the day you buy the shrimp or the same day you defrost it, also leftovers will not hold up well since the breading will get soggy

Which was it, black or green? Was it the breading or the meat that turned colour? Either way, throw it out
