Hey guys, let’s cut to the chase—if you’ve ever wandered the art supply aisle, squinted at a paint tube labeled “natural gouache,” and thought, “Wait, is that even a real thing, or just fancy marketing to get me to buy overpriced paint?” you’re not alone. As someone who’s been running a gouache paint supply shop for almost 10 years, I’ve fielded this question at least a hundred times. Artists ask at craft fairs, DM me on Instagram, even stop me at art workshops while I’m hauling my own paint kits around. And honestly? The short answer is yes—there absolutely are natural gouache paints—but it’s not as straightforward as just “throw some dirt in a tube and call it a day.” Let me break this down without all the stuffy art jargon, promise. Gouache Paint
First, let’s recap what gouache even is, because half the confusion here comes from people mixing it up with other paints. Gouache is that opaque, water-based paint, right? Think of it as watercolor’s thicker, more bold cousin—you can layer it, cover up mistakes, and it dries to a matte finish (unless you get the matte version vs. a slightly shiny one, but that’s a tangent). The key ingredients in any gouache, natural or synthetic, are pigment, binder, and extender. That’s the base triad every paintmaker uses. Now, “natural” just means those ingredients come from natural, non-lab-made sources, not chemical formulas cooked up in a lab.
So let’s start with pigments, because that’s where most natural gouache gets its personality. Natural pigments are basically ground-up stuff from the earth or plants—iron oxides for reds, yellows, browns; charcoal for blacks; titanium dioxide used to be natural (from mineral rutile, not the synthetic lab stuff now) for whites; even things like indigo from plants for blues. Wait, but hold on—you can’t just grind up a rock and turn it into paint. That pigment needs to stick to the paper, right? That’s where the binder comes in. For natural gouache, the binder is usually something like gum arabic, which you get from the sap of acacia trees. That’s a big one—synthetic gouache often uses acrylic binders or modified glues, but natural ones stick to gum arabic as the main binder.
Extenders are the fillers that thin the paint a bit so you don’t need a ton of pigment to make a full tube. For natural gouache, those extenders are things like kaolin clay or talc, both mined straight from the ground, no synthetic additives. Compare that to modern mass-produced synthetic gouache, which might use things like calcium carbonate or even plastic-based fillers to cut costs. The big difference here is that natural gouache’s ingredients are all derived from renewable or earth sources, so they’re often more eco-friendly, less irritating for people with sensitive skin, and yeah, they have that unique, rich tone that lab-made pigments just can’t replicate.
Wait, but let’s talk about the catch here—natural gouache isn’t perfect. Let me tell you a story from when I first started out, messing around with small batches of natural gouache in my kitchen (back when I was just selling out of a garage, not a real shop). I made a batch of that beautiful deep raw sienna using ground clay from a local quarry, gum arabic from a specialty supplier, and a bit of kaolin. It looked amazing when it was wet, but once it dried? It was chalky. Like, I could rub it right off the paper with my thumb. Why? Because natural pigments don’t have the same binding power as synthetic ones. The binders used in natural gouache are a bit less flexible, so when the paint dries, it can crack or flake if you layer it too thickly, or if you apply it to a rough surface that doesn’t grip well. Also, natural pigments are often less consistent. One batch of red iron oxide might be a little warmer or darker than the last, because the mineral composition of the quarry changes slightly every season. That’s a plus for unique tones, but a minus if you’re working on a large commissioned piece and need exact color matching every time.
And let’s not get this twisted—“natural” doesn’t mean “non-toxic.” A lot of old natural pigments are actually super toxic, like lead white or cadmium red, which were used in gouache back in the 1800s. We still see some cheap “natural” gouache on the market that uses these toxic pigments to save costs, so you have to be careful. At my shop, we only sell natural gouache that uses non-toxic, food-grade natural pigments now—we stopped carrying any with lead or heavy metals a few years back, after an artist told me she was using it for kids’ craft projects and was worried about her niece’s hands. That’s the kind of stuff that matters.
Now, let’s clear up the marketing hype, because a lot of brands slap “natural” on their paint tubes just to charge more. You’ve probably seen it too—$50 for a single tube of gouache labeled “100% natural.” Let’s be real: no gouache is 100% natural, because even the purest gum arabic has to be processed a little, and you need small amounts of preservative to keep the paint from going moldy (water + organic ingredients = bacteria central, am I right?). So most reputable natural gouache brands will call themselves “natural-derived” or “natural-formula,” which is the real deal. The fakes are the ones that just use a tiny bit of natural pigment mixed with mostly synthetic binders and fillers, then mark it up 30% for the “natural” label.
As a supplier, I get why artists are obsessed with natural gouache lately. More and more people are switching to eco-friendly art supplies, tired of supporting brands that use plastic packaging (we use recyclable tubes for all our natural gouache, by the way) or toxic ingredients. Also, the texture is different—natural gouache dries a little softer, more velvety, than synthetic, and the color has that depth you just can’t get from lab-made pigments. I had a freelance illustrator come to me last year, she does botanical art, and she swears by our natural sap green—she says it makes her paintings look like actual leaves, not just flat green. That’s the kind of feedback that makes running this shop worth it.
But let’s be honest, natural gouache isn’t for everyone. If you’re a student just starting out, working on a budget, or doing large pieces that need uniform color across 50 tubes, synthetic gouache is probably the better call. It’s cheaper, more consistent, and less likely to flake if you’re heavy-handed. But if you’re a professional artist chasing that unique tone, eco-conscious, or tired of synthetic paints that feel a little generic, natural gouache is absolutely worth testing.
I’ve seen a lot of new brands popping up lately claiming to sell natural gouache, but most of them haven’t done their research. A while back, a guy messaged me saying he was making natural gouache in his basement, using only dirt from his backyard and store-bought glue. I asked him about the binder, and he said he was using white school glue. Let’s just say that batch would have cracked and peeled within a month—school glue isn’t designed to mix with paint pigments for long-term use. That’s the problem with DIY natural gouache too; it’s easy to mix up something that looks fine for a week but falls apart later.
For anyone who’s curious to try real natural gouache, the thing to look for is the ingredients list. It should say things like “gum arabic” as the binder, natural pigments (iron oxide, indigo, charcoal, rutile titanium dioxide), and maybe a small amount of potassium sorbate as a preservative. If you see “acrylic polymer” or “modified starch” listed, that’s synthetic or semi-synthetic, so it’s not pure natural formula.
At my shop, we’ve spent over a year testing batches of natural gouache to get the formula right—we fixed the flaking issue by adjusting the binder ratio, so now it’s flexible enough to layer without cracking, while still keeping that rich natural tone. We work with a small mill in the Pacific Northwest that sources all our natural pigments locally, so we can track exactly where every tube’s ingredients come from, which is a big deal for us. We even do custom mixes for artists who want specific natural shades, like that deep umber from Oregon’s coastal clay or a soft rose from crushed beetroot (wait, beetroot pigment is real, by the way—makes a beautiful muted pink that’s perfect for skin tones).
I know this topic can be confusing, especially with all the marketing noise out there. A lot of artists get frustrated because they thought they were buying natural, only to realize it’s just regular paint with a fancy label. That’s why I love answering these questions—cutting through the BS and telling it like it is. Natural gouache isn’t some mythical, perfect paint, but it’s a real alternative to synthetic, with its own benefits and tradeoffs.
