How Many DMC Colors Are There for Diamond Painting? A Corporate Buyer's Honest Take

The question I hear most often from other corporate buyers is, “How many DMC colors are there for diamond painting?” My honest answer: the count is a starting point, but it’s usually a distraction. The number doesn’t tell you whether a kit uses a readable color key, whether the thread or drills will match the chart, or whether the vendor will stand behind a batch that goes wrong.

Here’s where my opinion comes from. I’m an office administrator for a 280-person company with three locations. Since 2020, I’ve managed all internal and client-facing gift ordering—roughly $40,000 per year across seven vendors, which works out to 60–80 orders annually. I report to both operations and finance, so I care about delivering quality, not just choosing what looks nice on a screen. People assume a long color list means a more impressive product. Sometimes that’s true, especially for gradient effects in detailed diamond paintings. But a broad palette isn’t what makes a kit successful. A 24-color design with accurate DMC codes will always beat a 50-color design where the numbers are wrong.

First, the DMC Number Everyone Wants

As of January 2025, the solid DMC color chart—the one most diamond painting suppliers use as a reference—is listed at 465 colors on DMC’s official chart. The full DMC catalog is larger once you add specialty threads, and you’ll also see 447 or 450 quoted by suppliers. In my experience, lower numbers usually mean their chart hasn’t been updated as new shades were added.

If you want my practical take: the total isn’t the part that matters. A typical diamond painting kit uses a subset of 20 to 45 DMC colors, and a 45-color kit isn’t automatically better than a 15-color one. More colors can even mean more ways for a supplier to get the mapping wrong.

What the Color Count Doesn’t Tell You

From the outside, buying craft kits looks like an aesthetic exercise. You pick the prettiest design and the best frame. The reality is much more operational. The difference between a gift people finish and one they abandon is usually color governance—the system that keeps printed symbols, DMC codes, and physical materials aligned from sample to mass production.

Most buyers focus on the design and the price. The part they miss is how the supplier controls color matching across an entire order. The question everyone asks is, “Which are the best diamond painting kits?” The question I now ask is, “Which supplier can prove that every bag in this order matches the chart?”

What a 300-Kit Order Taught Me

In 2023, I approved a 300-kit order of custom cross stitch Christmas ornament kits. We printed a small company logo and a holiday greeting on the canvas, and the sample looked charming. The production run did not match it. The printed color key was low-contrast, two similar shades were nearly impossible to tell apart, and some thread bags didn’t show their DMC codes. Within a week, I received seventeen emails from recipients asking which red they were supposed to use.

The rework cost us roughly $900 in replacement thread plus about sixty hours of coordination. I also had to explain to my VP why the “nice” vendor didn’t catch it. From that point, I stopped measuring kits by color count and started measuring them by sample-to-production consistency. Now I ask for a printed PDF proof of the color key at actual size before we approve production.

What I Compare Instead

People still ask me, “Which are the best diamond painting kits for corporate giving?” My answer depends on volume, timeline, and customization, but my checklist is consistent:

• Are DMC codes on the physical products? Thread bags, diamond drill packets, and color keys should use the same numbering language so replacements are easy.
• Is the canvas print legible? Symbols need contrast, especially at the edges of a canvas or under imperfect lighting.
• Will the supplier commit to same-batch production? If there is a gap between sample approval and manufacturing, colors can shift. I want the batch date and dye lot recorded on the invoice.

I also prefer authorized DMC inventory. When ordering smaller quantities, I use the official DMC store; for volume, I use an authorized wholesale distributor. That route is rarely the cheapest per unit, but it removes a lot of guesswork about code authenticity, and the invoicing is clean enough for our finance team.

The Shift I've Seen in Corporate Gifting

When I took over purchasing in 2020, corporate gifts were mostly branded merchandise: mugs, notebooks, and the usual logo pens. What was best practice in 2020 doesn’t necessarily fit 2025. In 2022, remote and hybrid teams made us rethink gifts that could be done at home. We started buying experience-style presents: cross stitch kits, diamond painting kits, and custom paint by number kits that people could complete on their own time.

Last year, we ordered a custom paint by number kit of our headquarters for employees celebrating five-year anniversaries. The finished pieces showed up in offices and kitchens—they became home decor rather than landfill. And the recipients didn’t ask how many DMC colors were in the kit. They asked whether it was enjoyable and whether the colors made sense.

The fundamentals of procurement haven’t changed. I still need clear specifications, accurate samples, truthful invoices, and reliable delivery. But the execution has changed: buyers like me now need to understand print resolution, canvas texture, and color standards. That’s not a bad thing. It just means the old “pick from a catalog” habit doesn’t serve us anymore.

Give Me the Number, but Choose by the System

Let me address the obvious counterargument: surely a bigger color count makes a kit more valuable? No, because count is not accuracy. A 35-color kit with carefully matched DMC codes will always beat an 80-color kit where the codes are decorative—or worse, internally inconsistent. The standardized DMC system is valuable precisely because it gives you a common reference for replacement and quality checks, not because the number of colors impresses anyone.

There’s something satisfying about ordering 300+ kits and seeing photos of completed projects in return. That payoff comes from accurate color mapping, clear charts, and suppliers who stand behind their work. So next time someone asks how many DMC colors there are for diamond painting, you can say 465-ish and send them to the official chart. Then ask the follow-up that actually matters: which color system is this supplier aligned to?
