Can You Sell Dark Side of the Moon Prism Art on Etsy? The 'It's Just Physics' Myth

There is a particular listing that shows up on Etsy every week, in a hundred slight variations: a black background, a white beam entering a triangle from the left, and a six-colour spectrum fanning out to the right. Sometimes it is a sticker. Sometimes it is a nursery print, a shower curtain, a stained-glass suncatcher, a laser-cut wooden wall panel, or an embroidered patch. Almost none of them say "Pink Floyd" anywhere.

The seller's reasoning is usually stated out loud in the shop announcement or the listing description, and it is genuinely a good argument: a prism splitting white light into a spectrum is a physical phenomenon. Newton demonstrated it in the 1660s. You cannot own refraction.

That is correct. And it is not the reason the listing gets removed.

The honest half of the myth

Start with what is actually true, because most posts on this topic skip it and the reader can tell.

You cannot trademark or copyright light refraction. Nobody owns the physics. You can sell a diagram of a prism dispersing white light — Newton's own experimental sketches are centuries into the public domain, optics textbook figures are everywhere, and "spectrum" and "rainbow" are among the most heavily used decorative motifs on the internet. A shop selling prism-themed science art is not, by that fact alone, doing anything wrong.

More than that: the design's own origin story supports the seller. Storm Thorgerson of Hipgnosis, the firm that produced the sleeve, has described being reminded of an illustration in a photography book showing light refracting through a glass prism. The idea came from a physics illustration. Hipgnosis submitted seven concepts for the album; the band picked this one, partly because Pink Floyd's live shows were already known for their lighting. It fits the "it's just a textbook diagram" story rather well.

So the seller is not stupid, and they are not lying to themselves. They are answering the wrong question. They are asking whether the idea is protected. Enforcement runs on whether the specific execution is protected — and this particular execution has been sitting on the US trademark register for over a decade.

What is actually registered

Pink Floyd (1987) Limited holds a US trademark registration — Reg. No. 4236037, from application serial 85324805 — covering the prism as a design mark. The registration does not describe "a prism." It describes, in the flat bureaucratic language the USPTO uses for figurative marks, a white, triangular prism design with a beam of white light to the left and a spectrum of colours — red, orange, yellow, green, blue and violet — to the right of the prism, all appearing against a black rectangular background.

Read that description again next to the mental image of the listing. Every element a seller thinks of as "generic physics" is in it: the triangle, the beam, the colour order, the black field, the left-to-right orientation. The registration is not a claim on refraction. It is a claim on that arrangement, used as a badge of origin on goods.

This is the single most common failure mode in Etsy IP thinking, and it is not specific to Pink Floyd. The seller correctly identifies that the underlying concept is free, concludes that the whole design is therefore free, and never checks whether somebody registered a particular rendering of that concept. Sellers make the same error with Steamboat Willie now that it is in the public domain — the 1928 cartoon is free, the Mickey trademark is not.

There is a small cultural footnote that makes the point better than any legal argument. When the NSA's PRISM surveillance programme became public in 2013, a wave of protest graphics used a prism-and-spectrum image, and IP commentators immediately started warning designers off it. Nobody had to explain why a prism graphic evoked a specific band. That reflex — see the triangle and spectrum, think Pink Floyd — is precisely what trademark law calls secondary meaning, and it is what makes the mark enforceable.

The test is not "did I use a protected idea." It is "would a buyer scrolling past my thumbnail think this is official band merchandise, or that the band approved it." A black square with a white beam and a rainbow clears that bar for a very large share of shoppers.

Three separate rights, and you have to clear all of them

The reason "I removed the band name" does not work here is that the band name was never the only thing in play. Three independent layers sit on this image, and defeating one does nothing to the other two.

The trademark layer. Pink Floyd (1987) Limited holds multiple US registrations covering PINK FLOYD as a word mark and the prism as a design mark. Trademark rights do not expire on a schedule the way copyright does — they run as long as the mark is used in commerce and renewed. A design mark registered in 2012 and continuously used on merchandise can outlive everyone reading this.

The copyright layer. The sleeve artwork is an authored artistic work from 1973. The prism illustration itself was drawn by Hipgnosis designer George Hardie — a living designer who was still giving interviews about the cover at its fiftieth anniversary in 2023. A 1973 published work is protected in the US for 95 years from publication, which puts expiry deep into the 2060s, and in the UK the term runs from the author's life. Copyright here is not a near-term problem you can wait out. It is a problem for the rest of your selling career.

Copyright also catches something trademark might not. If you redraw the cover by hand, change the colours slightly, tilt the triangle, or run it through a filter, you have made a derivative work of a protected illustration. "I drew it myself" is a defence to copying the file, not to copying the work.

The rights-holder layer, which changed recently. In October 2024 Pink Floyd sold its recorded-music catalogue to Sony Music for a reported $400 million. The deal was widely reported as including name-and-likeness rights — the bucket that covers merchandising. Songwriting was not part of it, but merch was.

That matters more to an Etsy seller than any doctrinal point in this article. The reflexive assumption behind unlicensed band merch is that the rights holder is a set of elderly musicians with better things to do. As of late 2024 the merchandising interest sits with one of the three largest music companies in the world, which has a dedicated brand-protection function and an economic reason to use it. The calculus a seller made in 2019 is not the calculus in 2026.

How enforcement actually reaches a small shop

Most sellers picture enforcement as a cease-and-desist letter arriving in the post, giving them a chance to take the listing down and apologise. That is not the mechanism that hits marketplace sellers, and the difference is financial.

Pink Floyd (1987) Limited is a repeat filer in the US District Court for the Northern District of Illinois — the venue that has become the centre of gravity for so-called "Schedule A" litigation. The company has brought a string of actions there, including a 2019 case (1:19-cv-00759), a 2023 action against a sealed list of defendants (1:23-cv-03130), and two 2024 domain-focused suits: one against the operator of tommygunvideo.com (1:24-cv-01773), and one filed on 6 June 2024 against the operator of pinkfloydmerch.com (1:24-cv-04711), in which the court ordered the domain disabled. The complaint in that case made the rights holder's own framing explicit: the growth of online retail has made policing the marks progressively harder.

The Schedule A structure is what should worry a small seller. A brand owner files one action naming dozens or hundreds of online storefronts, listed only on a schedule filed under seal, and moves ex parte — without the defendants being notified — for a temporary restraining order. The first thing most defendants learn about the case is that their marketplace account is restricted and their payout balance is frozen. There is no letter, no warning, and no window to quietly delist.

This is not a historical pattern winding down. On 5 August 2026 — ten days ago — Merch Traffic, a Live Nation subsidiary, filed exactly this kind of action in the same court against unnamed e-commerce operators selling counterfeit merchandise tied to Nirvana, Bruno Mars, Harry Styles and The Notorious B.I.G. The filing seeks injunctive relief, an accounting of the defendants' profits, treble damages, and in the alternative statutory damages of up to $2 million per counterfeit mark. Music merchandise enforcement against small online sellers is an active, industrialised practice right now, and the Nirvana smiley face is caught in the same net.

There is a direct-litigation track too. In April 2025, One Fifteen — a company associated with David Gilmour — sued Florida-based Palm Coast Holdings over merchandise reproducing Pink Floyd imagery, reported to include designs from both The Dark Side of the Moon and The Wall. The claim was the familiar Lanham Act package: confusing similarity to registered marks, false suggestion of affiliation, and dilution. That case is a useful signal because the defendant was a US business selling merchandise, not an anonymous overseas storefront. The rights holders pursue both.

Where the line actually sits

The workable distinction is not "band name or no band name." It is whether your design reproduces the registered arrangement or genuinely goes its own way. In practice the tells that push a prism design into the danger zone are:

• Black background. The registration specifies a black rectangular field. A prism on white, cream, or a photographic background is already a different visual object.
• The single white beam entering from the left. This is a compositional choice, not a physical necessity. Light can enter from anywhere.
• Six bands in the exact ROYGBV order, fanning right at that angle. Real dispersion is a continuous gradient. The discrete six-stripe fan is a graphic-design decision that was made in 1972 and registered.
• A flat, hard-edged equilateral triangle rather than a rendered three-dimensional glass object.
• Anything wrapping the spectrum into a heartbeat line. Roger Waters suggested extending the rainbow around the back of the sleeve to meet the pulse trace; that combination is unmistakably the album, not a physics diagram.

Hit four or five of those and no amount of omitting the band name saves the listing. Hit none of them — a photographic glass prism throwing a real, continuous spectrum across a pale surface, or a scientific illustration in a different palette on a different ground — and you are selling optics art, which is exactly what you told yourself you were doing.

The part that gets sellers caught: tags and descriptions

Here is the failure that turns a defensible design into an indefensible one, and it happens in the fields sellers treat as invisible.

A seller carefully titles the listing "Rainbow Prism Light Spectrum Wall Art — Science Poster." Good title. Then, because they want the traffic, they fill the tags with pink floyd, dark side of the moon, dsotm, floyd art, classic rock poster, and write in the description: "Perfect for any Dark Side of the Moon fan."

That seller has just supplied the evidence. The tags establish the intent to trade on the association. The description establishes that buyers are expected to read the image as the album. A takedown reviewer does not need to make an aesthetic judgement about whether the triangle is too similar — the seller has already told them what the product is. Search-driven enforcement tools work on exactly these fields, which is why checking tags and descriptions rather than just titles is the difference between a scan that means something and one that does not.

The same trap catches album-art adjacent products generally. Sellers making Spotify code plaques and album-cover keepsakes run into it constantly: the physical object is generic, the artwork on it is not, and the listing copy names the artwork.

The safe lane

If you want to keep selling in this space, three moves cover most of it.

Design away from the registration, not just away from the name. Change the ground colour, the beam direction, the spectrum rendering, or the geometry of the prism. Any one of those is a weak change; two or three together produce a design that is recognisably about light rather than recognisably about an album. The safest version is a photograph of a real prism, which no registration covers.

Keep the association out of every field. Not the title, not the tags, not the description, not the shop section name, not the alt text on the images, and not the shop announcement. If your traffic strategy depends on the band's name, you do not have a physics-art shop, and no amount of design distance will fix that.

Sell the fan the object, not the IP. "Progressive rock fan" gift framing, "prism light spectrum art," and "1970s-inspired geometric wall art" are all honest positioning that reaches the same buyer without borrowing the mark. That last one is worth sitting with: the buyer who wants this poster mostly wants the aesthetic — high-contrast, minimal, seventies. That aesthetic is not owned by anyone.

The reason this myth is worth taking apart carefully rather than dismissing is that the seller's premise is right and their conclusion is wrong, and those are the cases where people lose money. Nobody owns refraction. Somebody owns that black square. The distance between those two sentences is where the takedowns live — and if you sell band-adjacent work at all, it is worth reading the broader rules on music and band merchandise and the Pink Floyd trademark guide before your next listing goes live rather than after.
