Octopus Color Spectrum
While many other underwater creatures adapted to see a wider section of the color spectrum than humans, cephalopod adaptation took a different turn. Remarkably the animals appear to be colorblind. Here we investigate a range of reflectance spectra of octopus (Octopus tetricus), compare them with the spectra of differently coloured backgrounds, and model the colours of octopus and backgrounds as they are seen by potential predators, while reflectance spectra of cuttlefish have been measured [12, 13, 14], the reflectance spectra of octopus.
A Kaleidoscope of Hues Octopuses can display an impressive spectrum of colors, ranging from deep reds and browns to bright whites, and even vivid blues and greens. These changes can occur almost instantaneously. They do not just change to solid colors; their skin can also exhibit complex textures, patterns, and even iridescent flashes.

This allows them to mimic their surroundings, whether it. The eyes of cephalopods like octopus, squid, and cuttlefish possess only one kind of photoreceptor, implying that they are colorblind, being able to see only in greyscale. This means that octopuses can only perceive colors within a narrow range of the spectrum.
The colors they can see are likely to be in the blue-green range, as this is the color that triggers the greatest response in their opsin cells. Researchers have conducted experiments to test the color perception of octopuses. An octopus's skin is a marvel of biological engineering, equipped with a complex network of pigment-containing cells called chromatophores.

These cells are arranged in layers, each containing a different type of pigment: red, yellow, brown, and black. When an octopus wants to change color, its nervous system sends signals to these chromatophores, causing them to expand or contract. Color Measurement Tools: Specialized tools like spectrophotometers can quantify the light reflected off the skin of an octopus.
This technology allows researchers to analyze the color spectrum and determine how various colors evolve in different settings. The color of octopuses has long fascinated scientists and observers alike. Octopuses can rapidly change color and texture to camouflage themselves from predators and prey.
Octopus Color Change
But what is their true, underlying color underneath all those chromatophores? The answer is complex and sheds light on the amazing biology of these cephalopods. Some researchers have found that the chromatophores, the color changing cells, of an octopus's skin actually do respond to some wavelengths of light due to the presence of a protein called opsin. This opsin is the same protein that detects the light in our eyes.
