Video, captured by diving excursion company OceanGate Expeditions, shows a level of colour not seen by the human eye since 1912.
The team filmed the historic vessel in high video resolution – around 8,000 pixels wide – allowing them to capitalise on high-zoom features without losing image quality.
The ship's enormous portside anchor can be clearly seen, as can a single-ended boiler that fell to the seafloor when the vessel broke in two and sank 12,500ft.
The Titanic's 200lb anchor chain is also visible in the dark depths of the North Atlantic.

It comes after OceanGate Expeditions filmed the iconic lost vessel for the second time.
The group transported "mission specialists" to the Titanic, with them safely enclosed inside the submersible, Titan.
Their expedition was carried out during an eight-day mission this summer.
Stockton Rush, OceanGate Expeditions President, said in a statement: "The amazing detail in the 8k footage will help our team of scientists and maritime archaeologists characterise the decay of the Titanic more precisely as we capture new footage in 2023 and beyond."
Titanic diver PH Nargeolet added that the crew was met by "the enormous 15-ton anchor still located on the deck of the shipwreck and the shackle that was originally attached to the main mast that has now collapsed".
He continued: "Later in the video, you see three round structures along the inside of the railing.
"These are the triple fairleads that were used to feed the docking ropes to the bollards on shore to secure the ship to the dock when the Titanic was at port."
Titanic's solid bronze capstans, used to move heavy weight around with rope, cables or chains, were spotted for the first time since the ship sank.
Titanic's rail has collapsed and fallen away from the ship – again, an observation not recorded before.

Veteran Titanic diver Rory Golden said: "One of the most amazing clips shows one of the single-ended boilers that fell to the ocean's floor when the Titanic broke into two.
"Notably, it was one of the single-ended boilers that was first spotted when the wreck of the Titanic was identified back in 1985."
According to the National Oceanic and Atmospheric Administration, the hull and structure of the ship is likely to collapse within the next 40 years.
The Titanic sank on April 14, 1912, after colliding with an iceberg four days into her maiden voyage from Southampton to New York.
A total of 1,517 of the 2,224 passengers and crew on board died.
The wreck was found deep at the bottom of the Atlantic, about 400 miles from Newfoundland in Canada, in 1985.
