Most intelligent Mimic Octopus in the world
Why Worldbuilding Stack Exchange recommends it
Worldbuilding Stack Exchange answerers point people to it as a real-world example of animal camouflage and expressive skin colour changes when designing invisible, color-signalling or cephalopod-like creatures.

What it is
A short 2010 clip showing a mimic octopus changing its shape, colour and posture to imitate other sea creatures. It is a brief nature video from the channel FullKanal with no narration details given beyond the title and tags.

Since the creature is solid then just making it transparent is very hard, for the reasons already discussed. That leaves two options: Bending Light The creature could somehow bend light around itself, as is being experimented with in various labs around the world right now. We already have materials that are invisible to some frequencies, so it's theoretically possible to do the same with visible light. Active Camouflage This is not true invisibility as it has to present the same image to all observers but it would be effective at reasonable distance. You re-colour yourself dynamically to match your background. The chameleon does this but quite slowly, there are much faster and more dynamic

How octopi might use clothing Octopi are an incredible order - and it just so happens that some species actually use something that could loosely be considered clothing. Coconut octopi have been observed carrying pairs of half-coconuts or shells around with them to wear as camouflage and defense - as seen in this video [LINK] . They pull the pieces together over themselves when they are lying in wait for prey or threatened. Now this is not really clothing as it is only put on when they come to rest, but you can see how the concept could be adapted into a sort of suit of armor. One of the benefits of being in the water is that it can support the weight of such armor, making it more practical

Binary Consider how complex a computer is and what it is capable of, yet all its code is composed of almost the most rudimentary elements possible: zeros and ones (binary code). So, the computer software you and I are using right now to communicate is being transmitted to each other via binary and all languages the human race has ever developed have also been translated into binary. In addition, all philosophical texts, all mathematics of superstring theory, general relativity, all sciences, all humanities, all arts have been translated into binary formats that we access all day long while using digital devices. So, even just sequences of black and white blocks of colors on chromatophores ar
