Rainbow Corner Accent Wall DIY

There are some rooms that just ooze charm even when the room is completely empty—tall ceilings, large windows, details in woodwork or molding are all things that can give a room a head start on charm. Sometimes, however, you have a room that has none of those details and it can feel really difficult to add that personality into the space, and all the bedrooms in our ’60s ranch home have that particular challenge. When converting my office/craft room into a playroom for our daughter, the first thought I had when I pulled out all the office stuff was “Wow. This looks so boring.” And I knew I had to add a fun detail to the walls to make it come alive a bit.

I was browsing through the A Color Story App Instagram feed a few months ago and came across this photo and I loved the neutral rainbow that spanned the corner of the wall (thanks internet for solving the mystery and letting me know Grace Dille designed it at the Flea Style—it’s so good!). Since you mainly see the far corner of the playroom as you pass it in the hallway, I thought a similar corner rainbow would be perfect for the playroom happy vibes. Of course, I had to add a little more pink shades to the color mix as I just couldn’t help myself …

-paint in various shades for each rainbow strip (I used from top to bottom Valapar’s Champagne Pink, Baby Blush, Opal Blush, Warm Cappuccino, and Pink Wink)
painter’s tape and scissors
-white paint (or whatever color your main wall color is)
-paint brushes and rollers (I love these brushes)
-cardboard and light colored color pencil for guide

First, you’ll want to use pieces of painter’s tape to make the largest arch of your rainbow. I would tape where you want both sides to end, then put tape at the highest point where you want the middle of the arch to be, and then fill in the rest from there. You can make your rainbow tall and skinny, fat and wide, lopsided—whatever you want!

Once you get a general outline of where your outer rainbow band will be, you can play connect the dots with the tape and get your outer edge taped off. Depending on how many colors you want to use in your rainbow, you’ll need to decide how wide you want each rainbow stripe to be. I wanted my stripes 10″ wide, so I cut a 10″ piece of cardboard and then taped a very light pink colored pencil to the other side so I could trace a 10″ gap and know where to place the next strip of painter’s tape. I suggest using a very light colored pencil for this as I’ve had too many instances of using regular pencils for marking where it was difficult to cover over with my light colored paint. Use your width tracer and run the non-pencil side against the tape mark of your rainbow band so it creates another line 10″ away. Use your painter’s tape to tape just on the outside of the pencil mark so your marks will be painted over and hidden. It can be a little difficult to make an arch with straight painter’s tape, so I would either suggest cutting a piece of tape down the middle so it’s a lot thinner (and easier to bend into an arch shape) or you can make some cuts into the outside edge of the tape to about the halfway mark so you can bend the tape to your line more easily.

Once you get your first section taped off, you’ll want to take the main color of your wall (white in my case) and paint some of that color paint all along the edges of your rainbow band where the tape meets the rainbow. It may seem like an unnecessary step, but using the wall color where the tape seam hits will actually give you the cleanest line of your rainbow color when you go to take the tape off! Basically, if there is going to be any paint bleed on the tape line, the bleed will be the wall color and so it will disappear into the wall when you go to take the tape off. Believe me, I’ve done it without this step in the past and I’ll never skip it again! It works really well.

Once your wall color is dry, paint your rainbow band color onto the stripe with as many coats as you need (with adequate dry time in between). Once your paint is dry, you can peel off the tape and your first stripe is done!

  Repeat by taping off the outer edge of the next layer and then using your cardboard width tracer to show you where the next tape line should be. Tape your second line, paint with your wall color along the edges, and fill with your main color. Repeat until each layer of your rainbow is done.

You are welcome to measure out precisely the space between each rainbow band so they are all perfectly spaced, or you can just eyeball it like I did. I’d say it came out really cute without having to spend a lot of time trying to make it all perfect. Light Fixture / West Elm, Art Print / Society 6, Wicker Baskets / Container Store  I love that this is a relatively easy statement wall (mostly a lot of waiting between coats), but it turned out SO CUTE and I adore it. It makes me so happy to pass by the wall every day now and being in that room feels so much more joyful than it did before. One thing I decided on before starting the wall is that I would be OK with an imperfect rainbow shape, so I will say that also helps the process go a little faster if you aren’t measuring every arc and curve to perfection. Also, feel free to complete your corner rainbow in whatever colors you want to fit your decor! I almost did this in an all neutral scheme (like tans and camels), buuuuuut I missed the pink too much so I had to add some in—whatever works for you! We’ve got a ton of statement wall DIYs in our archive so browse those too and see if any strike your fancy for your space! Oh, and in case you aren’t the DIY type, they also make lots of rainbow decals for walls as well for a similar feel… xo. Laura

  • Thank you so much for sharing this project! I made my own version in a green palate for my nursery and love it: https://www.reddit.com/r/BabyBumps/comments/rntk22/hand_painted_mural_hand_sewn_mobile_childhood/

    • Thanks for sharing this! I used this tutorial and even the same paint colors in my daughters bedroom and it turned out AMAZING. So happy you shared this!

  • Just wondering if you cut the west elm lamp rod to size? I have bought the same one but it is much longer.

  • Love this! Planning mine out now. Just for reference, how wide and how tall is your rainbow?

  • I just did this and love it for my daughters room. What kind of curtains would you recommend? We did the rainbow on one wall and painted the other 3 the champagne pink. The window is on the champagne pink wall.

  • My daughters room layout is very similar so I did this and wow, do you make that look easy. Making arches with tape is not easy. Thank you for all the details bc this non-creative lady is clueless!

  • I love this rainbow and I’m thinking to put it in one of the kids bedrooms. I’ve googled some diy rainbows to get an idea of how to do it best. Is there a special reason you started with the biggest bow and not with the smallest as most people do? Would be glad to now about your arguments … thanks!!

  • Thank you for sharing this! My daughter was begging me for a pink room and I just couldn’t bring myself to do it. Came across this tutorial while browsing through Pinterest and thought it would be the perfect compromise (and project to work on while being quarantined the last few months…). Great instructions, went with similar colours from Benjamin Moore, turned out beautifully. And my daughter (and I) are obsessed with how sweet it looks?

    • I would love to do this for my daughter! Would you mind sharing what colors you used?! I’m struggling to pick them

      • All colors are from Valspar, and listed towards the beginning of the tutorial 🙂
        Starting from the largest outer band: Champagne Pink, Baby’s Blush, Opal Blush, Warm Cappuccino, and Pink Wink

  • Do you have an idea of how much paint you used? Love this color scheme.

  • Hi! Love this DIY tutorial, thanks so much! Do you mind sharing the brand and colors of paint you used for the rainbow?


  • This rainbow, especially the colors, is so good! Great inspo for my kids playroom. Love it.

  • Beautiful! I want to do this in my girls room. What are the paint colors/brand? They’re the perfect pastels!

  • This is so adorable!! I would love to do this in a corner of my daughters bedroom. Would it be possible, do you think, to tape off all the bands at once so you can paint all the colors at once and save on the drying time?

    • Hi! I really want to do this in my toddlers bedroom! But for some reason.. im just confused on how we get the white gap evenly lol. I read through the post a few times.. once we paint white after we put painters tape on, do we paint over that wirh the color.. or you start painting after the white. Lol

      • I actually just painted this in my toddler’s room using the instructions. I found it easier to buy 2 inch painter’s tape and use that between each rainbow arch so the white gap would be 2 inches wide. I took the tip to put white paint on the edges of the painter’s tape (painted the white both sides of the same tape since I was using wider tape and didn’t need to double up on tape for each side of the white gap). Then I went over the white with the pink color so I still had clean lines and minimal bleed. Hope that helps.

        • So you didn’t do the slits to allow for bend? I’m confused about how the colored paint is in a straight line when there are slits in the painters tape

  • OH MY GOSH! This room is so magical. What a beautiful space. I’m obsessed

  • Hi! Love this so much! Can you please share where you got that cute little table and chair? TY! 🙂

  • This is great (and so simple).

    Adding to your tip about using a light coloured pencil, I take it one step further and use a light coloured aquarell/water colour pencil so that if you don’t cover the line or it ends up in the wrong spot you can clean it off the wall with a damp cloth.

  • This is the cutest thing I’ve ever seen! I’m obsessed!


  • This is so cute! I would also love to hear about your new storage solution for your craft supplies- we’re also looking at converting a craft space to a play room but I’m at a loss as to where to put all my stuff now!

    • Yes, I’ll do a post on that eventually, still figuring it all out!


  • I love this so much! Been dreaming up ways to handpaint one of the walls in my office with a pattern and this look is inspiring me!

  • I wonder if y’all could start including the names of the plants you use in your rooms? I love the wild fern-looking plant and I’d love to know what it is!

  • You always do the coolest d.i.y.’s I’m not even really much of a pink person…more greens and blues…but I love the shades of pink you pick. Your home is truly beautiful!

      • This is so cute! I want to create something like this for my girl’s nursery. Can you tell me how much paint you use for each strip of paint?

  • I am obsessed with those colors! What a creative idea, Laura. I especially like that it goes onto two walls. And that print is perfection. Thanks for sharing!

  • I love the colour scheme you used! So cute! 🙂
