Just like any other cichlid they will match their surroundings. If you say otherwise, your absolutely wrong.
I sure hope that wasn't directed at me, Marshal?

I've kept well over 100 different
species of fish, scores & scores of them cichlids (just like FH) over a black background. Sometimes using natural sand as substrate, sometimes over light colored gravel, and in some cases using darker grey gravel.
I have NEVER once, in these HUNDREDS of species of fish, experienced anything like what you will read about from those that have never tried it.
Not once, ever, especially with
red fish. As a matter of fact, on cichlid-forum.com, which has the largest membership of cichlid keepers on the WWW, with close to 60,000 members world-wide, the vast majority of members use black as a background color. including those who keep red cichlids, such as Red Empress, Red Head Tapajos, Red Devils, etc.
Thousands of CA, SA, African, and even FH owners on that site, and the #1 color for background has always been black. Even way back in the day when I was a mod on that site black has always been the preferred background color.
Try going over to the CA/SA media lounge here on MFK & attempt to tell everyone that you can't or shouldn't use a black background as it will wash out a lot of their fishes colors. You will get laughed off of the forum.
Try telling someone that owns one of Happy's Red Mammons that they shouldn't keep their fish in a tank with a black background, or over dark substrate, and they will LOL.
On the Taiwan breeders website they even state:
P.S.¡G For better fish colour expression of, it's suggested to select the black colour as background layer.
Yes, the color of substrate, background, and lighting used, can have an effect on certain fish, and their colors, but that does not equate to a black background having a negative effect on the color of a mature male FH, including the color red.
