That DIY colour block gallery wall you’ve been seeing on Pinterest? I finally built one last March and it was easier than I expected once I stopped overthinking the color combos. Look, I’m not a professional decorator. I just got tired of staring at a blank space above my sofa and wanted something playful without painting the actual wall. So I grabbed some affordable frames from IKEA, three coordinating paint colors, and arranged them in a simple grid. The best part? I can swap the prints out whenever the mood strikes. No commitment. No nails in the wrong spot. (Okay, maybe one nail in the wrong spot.)
Why a Colour Block Gallery Wall Felt Like the Right Move Right Now
I’ve been seeing these dopamine decor trends floating around and honestly I wanted in. But re-painting an entire wall felt like a lot of work for something I might change my mind about in six months. That’s where the gallery wall DIY came in. It gives you that bold accent wall pop without locking you into one paint color forever.
Here is what sold me on this accent wall idea over a painted wall:
- You can take the whole thing down in ten minutes. Try doing that with a brush and roller.
- It costs way less than you think. I spent about $40 total on frames and paint.
- When my friend says “that ochre is so last season” I just swap one print for a different shade. No drama.
Spring feels like the right season for this too. The light is better, you are already in a mood to refresh things, and honestly winter gray just makes everything look sad. A color block wall art setup like this wakes up the room instantly.
Picking the Frames Without Overthinking It (Mostly)
Not gonna lie, I stood in the frame aisle for way too long. There are so many options and I kept second guessing myself. Here’s what I landed on: standard white matte frames, all the same size except one that is slightly thinner because I grabbed the wrong one. That lack of symmetry actually looks intentional now.
I used nine frames in a three by three grid. Some people do uneven numbers like five or seven for a more organic look. Fine. But I wanted a clean grid that screamed “I planned this.” So I went with square frames from the Target dollar spot section (yes, that exists and yes, they were like three bucks each). They are lightweight plastic but nobody can tell once they are on the wall.
The key here is to keep the frames neutral so the paint colors do all the shouting. White, black, or natural wood work best. Don’t add ornate gold frames unless you want your gallery wall to look like a Victorian parlor. Unless that is your vibe. In which case go for it.
Choosing Paint Colors That Don’t Fight Each Other
Ok so I am not a color expert. I just stood in the craft store aisle holding paint samples against each other until something felt right. I went with dusty pink, muted ochre, and a sage green. Not exactly groundbreaking I know but they looked good together in my living room which has warm beige walls.
Here is a practical tip: pick one light color, one medium tone, and one darker shade. That gives your color block decor enough contrast to actually read as a deliberate design choice. If you pick three pastels it just looks like faded Easter eggs. If you pick three dark shades it looks like a moody bar. Neither is wrong but decide which vibe you actually want.
Also and this is the weird specific detail I promised: I accidentally bought a tester pot of a color called “rusted carrot” and now one frame has an orange print that I keep telling myself is seasonal. It is fine. It adds personality. My point is you can mess up the paint selection and it still works because the grid structure keeps everything looking intentional.
Mapping Out the Grid on the Floor First
I taped out the full layout on my dining room floor before touching the wall. Look, I learned the hard way that marking a wall without a plan leads to uneven spacing and regret. So I laid all the frames down, adjusted them until the gaps looked even, and took a photo for reference.
Then I cut paper squares the exact size of each frame and taped them to the wall with painter’s tape. This step feels tedious but it saves you from hammering nails into empty space and then having to move everything. Trust me. I have filled more holes than I care to admit.
The spacing between frames matters more than you think. I went with two inches between each frame. Three inches felt too loose and one inch felt cramped. Two inches. That is my magic number. Your wall size might differ so test it with the paper templates first.
The Painting and Printing Shortcut That Saved My Afternoon
Here is where my DIY colour block gallery wall got weirdly efficient. Instead of painting paper or canvas for every single frame I used a mix of scrapbook paper and old printouts. I had a stack of plain white cardstock and some muted archival prints from a nature book I found at a thrift store.
I painted three of the frames’ backer boards directly with the acrylic paint. A thin layer dried in about fifteen minutes. Then I cut the scrapbook paper to size and slid it into the other frames. The mix of painted boards and patterned paper gives it texture without making me paint twelve individual prints.
One frame has a weird vintage cat drawing I found at a garage sale. It is tiny and slightly yellowed and makes me laugh every single time I look at it. That is the kind of personal touch a template blog would never tell you to add. But you should add one weird thing. It makes the wall yours.
Hanging Everything Straight (Yes It Took Two Tries)
I used command strips because I rent my apartment and my security deposit is already counting on me. For lightweight plastic frames these work perfectly. I just pressed them onto the back of each frame and followed the paper templates on the wall.
Not everything went straight on the first try. One frame tilted slightly to the left and I spent ten minutes convincing myself it was fine. It was not fine. I fixed it. Use a level. Borrow one from a neighbor if you don’t own one. Your eyes will thank you.
The whole process took about two hours not counting paint drying time. That is one afternoon of work for a wall that looks like it took actual planning and interior design knowledge. And nobody has to know you have a rusted carrot frame hidden in there.
Swapping Prints Later Is the Actual Best Part
After living with this colour block gallery wall for three months I already swapped two of the prints. It took literally thirty seconds. I just popped the frame open, slid out the old paper, and slid in a new one. The paint colors stayed the same but the artwork changed.
This is why I love this accent wall idea so much. You get the punchy color from the paint but you get the flexibility of a gallery wall. When my sister visits and says “I love that green” I can just pull the print out and hand it to her. No guilt. No “I spent hours on this so you cannot have it.”
If you want to get really fancy you can coordinate your print swaps with the seasons. Spring gets florals. Fall gets warm abstracts. Winter gets moody monochrome. Or just keep the same cat drawing forever. I am not judging.
Try this if you want a project that actually finishes in one weekend and makes your wall look like you know what you are doing. Pin your own version and tag me so I can see what colors you picked. I am always curious what combos other people land on.
