The Omega Rainbow series is a line of Roblox-made items that all share one bright red, blue and green texture, published between May 2014 and January 2019. Around twenty items carry the look, and seven of them are Limiteds, meaning items with a fixed supply that owners can resell and trade. The most valuable is Rainbow Periastron Omega, a 2,000 Robux (R$) sword from May 2014 that Roblox capped at 100 copies and that now carries a RAP of 454,741 R$. The cheapest is the Omega Rainbow Top Hat at 1,522 R$, because Roblox sold nearly eight thousand of those in a two-day window.
Quick answer: Omega Rainbow is a Roblox texture series of roughly twenty items released from May 22, 2014 to January 12, 2019. Seven are classic Limiteds, ranked from Rainbow Periastron Omega (100 copies) down to the Omega Rainbow Top Hat (7,898 copies). Eight more Omega Rainbow items are not Limiteds at all and still sit on Roblox's catalog, where the whole set costs 3,000 R$ at listed prices.
What is the Omega Rainbow series on Roblox? A Roblox texture line with seven Limiteds
Roblox has built dozens of families this way: pick one texture, then stamp it onto a helmet, a fedora, a sword, a cape. Omega Rainbow is one of the later ones, and it is easy to spot. Every piece runs red into blue into green in tight bands, and most of the descriptions lean on a time-travel joke.
The table below covers every Omega Rainbow item that is a Limited. It is ordered by what traders actually pay, which is not always the same order as RAP. RAP stands for Recent Average Price, Roblox's smoothed average of an item's sale history, where each new sale pulls the number about a tenth of the way toward it. Lowest ask is the cheapest copy anyone has listed right now.
| Item | Published | Original price | Copies | RAP | Lowest ask |
|---|---|---|---|---|---|
 Rainbow Periastron Omega |
May 30, 2014 | 2,000 R$ | 100 | 454,741 R$ | 5,000,000 R$ |
 Rainbow Omega Katana |
Jan 8, 2016 | 1,000 R$ | 586 | 47,962 R$ | 44,999 R$ |
 Omega Rainbow Helmet |
May 22, 2014 | 500 R$ | 451 | 11,772 R$ | 21,650 R$ |
 Omega Rainbow Sword |
Aug 2015 | 500 R$ | 1,001 | 9,864 R$ | 9,999 R$ |
 Omega Rainbow Fedora |
Oct 1, 2015 | 250 R$ | 5,006 | 2,361 R$ | 3,000 R$ |
 Omega Rainbow Bowler |
Aug 2015 | 350 R$ | 1,200 | 2,360 R$ | 2,199 R$ |
 Omega Rainbow Top Hat |
Aug 26, 2016 | 500 R$ | 7,898 | 1,522 R$ | 1,549 R$ |
All seven went on sale with a stock number attached. That older format was called Limited U, and it is why copies of these items carry serial numbers, the little "#42 of 451" tag that says which copy you own. We explain how much those tags are worth in our guide to Roblox serial numbers. Four of the seven are hats, so they sit alongside the rest of the line on the classic hats collection, and the three gear pieces sit with the rest of the classic weapons on the swords and katanas pages.
Which Omega Rainbow item is worth the most? Rainbow Periastron Omega, by a wide margin
Roblox published Rainbow Periastron Omega on May 30, 2014 at 2,000 R$ with a stock of 100 copies, and it sold out. Its catalog description is a throwaway line about fighting magical unicorns in space, which tells you nothing about why it costs what it does. Two other things do.
The first is the copy count. One hundred copies puts it in the top tier of scarcity on Roblox, the band we call gems, and items that thin barely trade. The second is that it belongs to two families at once. It is the eighth blade in the Periastron line, Roblox's long-running set of glowing swords, and that line has its own collector base on top of the Omega Rainbow one. If you want the full run, we covered it in the Periastron series history.
Its RAP of 454,741 R$ badly understates it. The cheapest copy listed on Roblox right now asks 5,000,000 R$, roughly eleven times the RAP, and trader consensus sits far above the RAP too. That happens on any item with almost no sales: RAP only moves when someone sells, so on a 100-copy sword it can sit frozen for a year while asking prices climb past it. Treat the RAP as the last thing somebody accepted. Items in this band are all collected on the rarest Limiteds page.
Where did the Omega Rainbow series start? A 500 Robux helmet in May 2014
The Omega Rainbow Helmet came first, on May 22, 2014, at 500 R$. Its description reads "In the end light is all that's left," which is a strange thing to write on a rainbow knight helmet, and collectors have quoted it ever since. Roblox sold only 451 of them, the second-smallest supply in the family, and the cheapest listing asks 21,650 R$ against a RAP of 11,772 R$. Somebody who bought one at launch and still holds it is up roughly twenty-three times on RAP.
The Roblox Wiki's page on the helmet records that its texture was originally made by a player, twinny4u92, and reused by Roblox for the official item. That detail is community-documented lore, so don't price an item on it. What is certain from the catalog itself is that Roblox owns and publishes every one of these items.
Eight days after the helmet came the Periastron. Then the line went quiet for most of a year before Roblox started shipping Omega Rainbow items at a steady clip through 2015 and 2016.
Why is the Omega Rainbow Top Hat so cheap? Roblox sold 7,898 of them
Supply explains almost everything about this family, and the Top Hat is the clean example. Roblox listed it on August 26, 2016 at 500 R$ with a cap of 10,000 copies on a two-day timer, and 7,898 of them sold. Its RAP is 1,522 R$ and the cheapest listing asks 1,549 R$.
Compare that to the helmet from two years earlier: same 500 R$ launch price, 451 copies instead of 7,898, and a resale price about eight times higher. Nothing about the two hats differs except how many Roblox made. If you only remember one thing about buying older Roblox Limiteds, make it that.
The Omega Rainbow Fedora sits in the same spot for the same reason. Roblox sold it on October 1, 2015 for 250 R$ and put 5,006 copies into circulation, so it trades at 2,361 R$ with a lowest ask of 3,000 R$. It is one of the cheaper entries on the fedoras collection, and if you want the bigger story of that hat shape, our fedora family history runs from the classic through the Sparkle Time versions.
One quirk worth noticing: the Omega Rainbow Bowler has a lowest ask of 2,199 R$ against a RAP of 2,360 R$. The cheapest copy is listed below the average sale price. That is a small gap, and on an item with 1,200 copies it usually closes fast, but it is exactly the pattern the Deals feed is built to flag once you are signed in.
Can you still buy Omega Rainbow items from Roblox? Yes, eight of them
The seven Limiteds are resale-only now, but the series is bigger than its Limiteds, and eight Omega Rainbow items are still on Roblox's catalog at a fixed price today. Checked against Roblox's catalog in September 2026, those are:
| Item | Type | Price |
|---|---|---|
| Omega Rainbow Equinox | Hair | 500 R$ |
| Omega Rainbow Cape | Back | 600 R$ |
| Omega Rainbow Pauldrons | Shoulder | 600 R$ |
| Rainbow Omega Headphones | Hat | 400 R$ |
| Omega Rainbow Horns | Hat | 300 R$ |
| Omega Rainbow Shades | Face | 300 R$ |
| Omega Rainbow Sci Fi Visor | Face | 150 R$ |
| Omega Rainbow Bow Tie | Neck | 150 R$ |
That is 3,000 R$ for the entire on-sale set, the same price one copy of the Fedora asks on resale. None of these are Limiteds, so buying one is just buying an avatar item: you cannot resell it, you cannot trade it, and it will not gain value. If you want the look rather than the investment, this is the cheap way to get it.
A few Omega Rainbow items are neither Limited nor buyable. The Omega Rainbow Wanderer went off sale after January 2015, the Rainbow Basket of Solitary Omega opened to reveal the Rainbow Omega Antlers in March 2015 and then vanished from the catalog, the July 2015 Bandana of the Month ran on a 24-hour timer, the Omega Rainbow Equinox Hat ran for five hours in May 2017 at 100 R$, and the Omega Mage came from a Roblox toy code in 2018. Off sale is not the same as Limited: those items simply cannot be bought at any price, because Roblox never switched on resale for them. We walk through that distinction in how offsale Roblox items go Limited. The antlers, meanwhile, belong to a family we covered in the Antlers series history.
What drives the Omega Rainbow premium?
Three things, in order of how much they matter.
Copy count does most of the work. The three items under 600 copies carry RAPs between 11,772 and 454,741 R$. The two items over 5,000 copies carry RAPs of 2,361 and 1,522 R$. The two in the middle, both around a thousand copies, land in between at 9,864 and 2,360 R$.
Crossover membership does the rest at the top. Rainbow Periastron Omega is a Periastron first and an Omega Rainbow second, and the Rainbow Omega Katana pulls buyers from the katana collectors as well. A hat that only belongs to one family has one pool of buyers.
Age matters least here, which surprises people. The 2014 helmet beats the 2016 top hat on supply alone. Nothing in this family is old enough to carry the kind of premium that 2007 and 2008 items do.
What is the outlook for Omega Rainbow Limiteds?
Split the family in two and the picture gets clear.
The top pair are collector items. Rainbow Periastron Omega and, to a lesser degree, the Rainbow Omega Katana move rarely and price by whoever happens to be listing. If you buy in that band, expect to hold for years and expect the RAP on your portfolio page to lag what you could actually get. The items leaderboard is the fastest way to watch whether anything in that band actually sells.
The bottom four are ordinary stock with real supply. The Fedora, the Bowler, the Top Hat and the Sword all trade near their RAP with tight spreads, which means the cheapest listing sits close to the average sale price. You can buy one this week without hunting.
Do the resale math before you buy anything here to flip. Selling a classic Limited on Roblox costs a 30% marketplace fee, so you keep 70% of the sale price. Buy an Omega Rainbow Fedora at 3,000 R$ and you need to sell it near 4,300 R$ just to get your 3,000 back. On a hat with 5,006 copies and a resale price that has not moved much, that is a long wait for nothing. The scarce end is where the money in this family has always been, and it was scarce on day one.
None of this is financial advice. Limited prices move on collector sentiment, and a quiet item can stay quiet for years.

Omega Rainbow is a Roblox-made texture series of roughly twenty accessories and gear items sharing one red, blue and green color scheme, published between May 22, 2014 and January 12, 2019. Seven members are classic Limiteds with fixed supply. The rest are ordinary catalog items, and eight of those are still on sale.
What is the most valuable Omega Rainbow item?
Rainbow Periastron Omega. Roblox sold 100 copies at 2,000 R$ on May 30, 2014, and it now carries a RAP of 454,741 R$ with the cheapest listed copy asking 5,000,000 R$ as of September 2026. Nothing else in the family is close.
How many Omega Rainbow Limiteds are there?
Seven: Rainbow Periastron Omega, the Rainbow Omega Katana, the Omega Rainbow Helmet, the Omega Rainbow Sword, the Omega Rainbow Fedora, the Omega Rainbow Bowler and the Omega Rainbow Top Hat. Every other item wearing the texture is a normal catalog item that cannot be traded or resold.
What is the cheapest Omega Rainbow Limited?
The Omega Rainbow Top Hat, at a RAP of 1,522 R$ with the cheapest copy listed at 1,549 R$. Roblox listed it in August 2016 with a 10,000-copy cap on a two-day timer and 7,898 sold, which is why it is the cheapest of the seven.
Can you still buy Omega Rainbow items from Roblox directly?
Yes, eight of them. The Equinox hair (500 R$), Cape (600 R$), Pauldrons (600 R$), Rainbow Omega Headphones (400 R$), Horns (300 R$), Shades (300 R$), Sci Fi Visor (150 R$) and Bow Tie (150 R$) were all on Roblox's catalog in September 2026 for 3,000 R$ in total. None of them are Limiteds, so they cannot be resold or traded.
Which Omega Rainbow item came first?
The Omega Rainbow Helmet, published on May 22, 2014 at 500 R$ with 451 copies sold. Rainbow Periastron Omega followed eight days later on May 30, 2014, and the rest of the family arrived between 2015 and January 2019.
Do Omega Rainbow Limiteds have serial numbers?
Yes. All seven were sold with a fixed stock, which is the format that assigns each copy a serial number showing where it sits in the run. Lower serials, especially single digits, sometimes fetch a premium from collectors on scarcer items.
Is the Omega Rainbow Fedora a good first Limited to buy?
It is one of the cheaper ways into the family at a 3,000 R$ lowest ask, and with 5,006 copies in circulation you will always find a seller. Just do not expect it to move much: supply that large keeps the price flat, and the 30% marketplace fee on any resale means you need roughly a 43% price rise before you break even. Buy it because you want to wear it.
