Happy new year!! Do you know if the tank background and surrounding afeect the fish color? I am not talking about different light or anything, I am talking about white vs balck or dark blue backgrouns...Would the fish change its color or do fish camouflage?
I bought a turquaz dicus which looked pretty light colored and all red etc, howvere in my tank it is dark turquaz...similarly, a pigeon I bought loked to have white/silver stripes but now it's stripes are dark silver/pepper...They look healthy and eating very well.They have been like this from the day one? In one day, they changed the color (They were still in the bag in the tank and they changed the color).

So much to learn...I agree with you Stan, diffcult to find a person with 30+ experience
