Beautiful aquarium with both substrates!

I don't like colored gravel because it usually upstages the fish. The fish won't become more blue because of the gravel--usually their camouflage coloration is just lighter and darker. Brighter color comes from water condition, food, breeding, or competition, which is why some people use a mirror to get their fish to color up.

Natural gravel allows the fish to be the brightest object in the tank. I've often mixed black and natural gravel, or used dark pea gravel from a gravel yard for a darker substrate that still looks natural.

How is the puffer with the rivulatus?? My rivulatus are around 2.5” right now so I’m good with my bleeding heart tetras but seeing the size of your male I’m a bit concerned haha ?.
They grew up together. The puffer always minded his own business and my riv minded his.
Sadly I lost my puffer after a water change a while back. I suspect my big female had something to do with it. She seems to be the cause of a lot of problems.

So should I go with a dark blue sand or gravel being that they try to camouflage with the substrate?
I'm with the others, I prefer naturally colored substrates. Even with black, naturally black sand looks a lot better in a tank than artificially colored black gravel.

Cichlids camouflage in the sense that in dim light, or with dark substrate and background they trend darker, bright tank with bright light, substrate, aquascape, etc. they trend lighter. Not a 100% rule, but it's the trend.

It's a different thing than saying they (try to) match color, as in blue in the tank and they turn more blue-- cephalopods do that, cichlids not really. :)

That said, lighting can bring out, enhance, unnaturally exaggerate, distort, or muddy up colors. Bulbs vary in spectrum and some are better than others at bringing out color without exaggeration or distortion. The right bulb can make everything in the tank look sharper, including plants. Daylight with no lights and varying angles of indirect to direct sunlight really brings out the color in many fish.

Background, substrate, etc. can naturally complement the color of a species without the fish itself changing. So a lot of discus display nice with light substrate and light blue backgrounds, my kapampa gibberosa look good against a dark blue background (I also have some large, tall, rust-ish colored slabs standing in the tank that complement the background and fish), lot of SA fish look good with black background, etc. It's not always that the fish changes color or goes darker or lighter, certain lighting and surroundings can make the same colored fish look better.
