Deciding on the right imperial guard paint scheme is probably the biggest hurdle any Astra Militarum player faces before they even crack open a single pot of paint. It's a bit of a daunting task when you realize that "finishing an army" doesn't mean painting five or ten models—it means painting sixty, eighty, or even a hundred tiny soldiers who all need to look cohesive on the tabletop. If you've ever stared at a grey mountain of plastic and felt that slight sense of panic, don't worry, you're definitely not the only one.
The beauty of the Guard is that they aren't genetically modified super-soldiers or ancient space elves. They're just regular folks in flak jackets, which means their gear should reflect the dirt, grime, and harsh reality of whatever planet they've been dumped on. Whether you want to stick to the lore or create something completely from your own imagination, the color palette you choose sets the entire mood for your collection.
The Classic Cadian "Box Art" Style
Let's talk about the elephant in the room first: the classic green and tan look. Most of us got into the hobby seeing those Cadian Shock Troops on the box art, and there's a reason that specific imperial guard paint scheme is so iconic. It just works. The olive drab armor (usually Castellan Green) over the khaki fatigues (Zandri Dust) gives off a very traditional, 20th-century military vibe that feels grounded and "realistic" for a sci-fi setting.
The best thing about going with the Cadian look is the sheer amount of help available. Since it's the standard, you can find a million tutorials, and almost every paint brand has colors specifically designed to match this aesthetic. It's also a very forgiving scheme. If you mess up a highlight or your wash is a little heavy, it just looks like the soldier has been crawling through the mud. However, the downside is that you'll see this look everywhere. If you want your army to stand out at the local game store, you might want to tweak it or go in a different direction entirely.
Taking It to the Streets with Urban Camo
If the forest green look doesn't do it for you, an urban imperial guard paint scheme is a fantastic alternative. Think greys, blacks, and maybe a touch of dark blue. There's something incredibly menacing about a line of guardsmen dressed in "city-fight" colors. It makes them look like a specialized swat team or a gritty planetary defense force holding the line in a crumbling hive city.
One of the coolest ways to pull this off is by using different shades of grey for the fatigues and the armor plating. You could do a medium grey (like Mechanicus Standard Grey) for the cloth and a darker, almost black tone for the armor. To keep it from looking like a featureless grey blob from three feet away, you can add a "pop" color. Maybe their shoulder pads have a red stripe, or their weapon casings are a bright white or hazard orange. It breaks up the monotony and gives the eye something to lock onto.
Desert and Wasteland Themes
Desert schemes are probably the most "user-friendly" when it's time to actually sit down and paint. If you go with a tan, sand, or bleached bone color as your primary base, you can get through a lot of models very quickly. A heavy wash of Agrax Earthshade or a similar brown ink over a tan base coat does about 90% of the work for you. It settles into the recesses, creates natural shadows, and makes the model look "dusty" instantly.
When you're working with a desert imperial guard paint scheme, you can lean into the weathered look. Sponging on some dark brown or silver "chips" on the edges of the helmets and armor makes it look like the sand has been blasting the paint off during a long campaign. It's an easy way to add detail without needing the steady hand of a master surgeon. Plus, desert bases are a breeze to do—just some texture paste and a bit of drybrushing, and you're good to go.
Going Rogue with Custom Colors
This is where things get really fun. You don't have to follow the "real-world military" rulebook. If you want your guardsmen to wear bright purple armor with neon yellow fatigues because they belong to a flamboyant planetary noble's private militia, go for it. The "Your Guys" philosophy is one of the best parts of the hobby.
Using the Color Wheel (Simply)
If you're going custom, try to keep some basic color theory in mind so the models don't look messy. Generally, you want a main color for the fatigues and a contrasting color for the armor. If you pick colors that are opposite each other on the color wheel—like blue and orange or red and green—they're going to look very "high-contrast" and bold. If you pick colors next to each other, like dark blue and light blue, they'll look more subtle and unified.
The Power of Tints
Don't be afraid to experiment with weird tints. A very dark, desaturated teal can look amazing as armor over dark grey cloth. Or maybe a deep burgundy over a tan base. The trick to making a custom imperial guard paint scheme look "official" is consistency. As long as every model in the squad has the same colors in the same places, it'll look like a professional fighting force regardless of how wild the colors are.
Tips for Painting a Literal Army
We need to be honest here: painting 80 guardsmen is a marathon, not a sprint. If your imperial guard paint scheme involves fifteen different steps and three layers of edge highlights on every single belt buckle, you are going to burn out before you finish the first squad.
The Power of Contrast and Speedpaints
If I were starting a new Guard army today, I'd heavily consider using Contrast paints or Speedpaints. These are designed to base, shade, and highlight in one go. You prime the model in a light color (like Wraithbone or a light grey) and then "slop" the paint on. It flows into the cracks and leaves the raised areas lighter. You can knock out a squad of ten infantrymen in an evening this way. It won't win you a Golden Demon award, but they'll look great on the table, and more importantly, they'll actually be finished.
The "Assembly Line" Method
Batch painting is your best friend. Don't paint one model from start to finish. Instead, line up ten or twenty of them. Paint all the fatigues on all of them. Then paint all the armor. Then all the skin. By the time you get to the last model in the row, the first one is dry and ready for the next color. It's a bit repetitive, but it's the most efficient way to keep the imperial guard paint scheme looking uniform across the whole army.
Don't Forget the Bases
The base is what ties the whole look together. If you have a dark green and brown army, a bright, sandy base will make the models pop. If you have a light-colored desert army, maybe a dark, muddy base or a grey industrial base works better. The contrast between the model and the base is what makes them "read" well from a distance.
Final Thoughts on Your Platoon Look
At the end of the day, the best imperial guard paint scheme is the one that you actually enjoy painting. You're going to be spending a lot of time with these little plastic soldiers, so if you hate the color yellow, don't force yourself to paint a yellow army just because it looks cool on Pinterest.
Try out a few test models first. Take three different guardsmen and try three different variations of your idea. See which one was the most fun (or the least annoying) to paint. Once you find that sweet spot between "looks cool" and "is easy to repeat," you're ready to start your conquest of the galaxy. Just remember: the Emperor expects every man to do his duty, but he probably doesn't mind if they look sharp while doing it.
