A few weeks ago I ordered this rainbow hammer coral online. The hammer coral ended up getting stuck in a warehouse overnight and the water was probably about 50 degrees when it finally arrived. Now to this day the coral is healthy and open, but it looks bleached from the original pictures. I've heard how when coral is found in cold water it can kill off zooxanthellae algae thus causing this bleaching. I was seeing if anyone else had this happen to them and what the long term effects where. I'm assuming the color will come back, but how long does that usually take?

What kind of color is it missing? Zoox density usually dictates how "brown" it gets so if thats whats missing then it should recover faster with good water and lighting parameters
If its the rainbow colors that are now missing, that is due to missing color pigment and flouresent protein. That is harder and takes longer to get back - nutrition, right lighting (both spectrum and par) are more key and need to also make sure nutrients are not too high.
Nutrition - amino, fish poop/pee, dissolved organics, phyto, etc..
Nutrient - no3/po4
The latter, + low light may lead to over production of zoox and turning coral into ugly brown.
