DIY Modern Color Block Wall

I love white. Nearly every wall in my home is white. I love the clean, calming look of it.


Sometimes you just need to add a little color and fun to a wall! Especially a wall in your young daughter’s room.

Let me share with you the super simple steps to creating a gorgeous, modern accent wall. And bonus: The wall will remind you of neapolitan ice cream and your fun, carefree childhood days.

How to Create a Color Block Wall

Color blocking doesn’t have to be hard. The two key elements to color blocking are:

  1. An amazing design
  2. Crisp, clean lines between paint colors

Pinterest can be an amazing resource for finding all sorts of amazing ideas for a design. Also, just looking at everyday objects, patterns and artwork can inspire you. I’m currently loving the arches trend and therefore, I chose to create a mix of arches, adding some half-arches into the design as an extra dose of creativity and uniqueness. 

In order to get crisp lines when you are painting curved lines such as arches or circles, you need the right tool. Here is the magic tool: the Purdy Clearcut Elite paint brush. It’s amazing. It has stiff bristles that are perfect for creating really clean lines along trim or along a color block design.

Time to Complete: 1-2 Days

Purdy roller painting white paint on wall

Step 1: Apply a fresh coat of paint to your entire wall. 

This might not always seem necessary but it’s a great way to make sure that you’re starting with a really clean wall as the base for your design. 

I like to use the following Purdy products to get this job done quickly and easily: A paint tray, a paint tray liner, a 9” roller frame, a White Dove roller cover and a Clearcut Elite paint brush. The White Dove roller cover is perfect for a wall – it leaves a smooth, lint-free finish. Also, like I said previously, the Purdy Clearcut Elite paint brush will help you get really clean, crisp lines around the edges of your wall because of its stiff bristles.

Drawing out the color blocking design on the wall with a level and pencil

Step 2: Draw the design on the wall with a pencil

Using a level, measuring tape, pencil and string, draw out the design on your wall. To make my design, I first freehanded it to get a really solid idea of what I wanted. Then I went back and measured everything out to ensure that it was perfect. 

To make perfect arches I used a pencil and a piece of twine. You could use string instead of twine. It doesn’t matter.

Drawing an arch on the wall using a string and a pencil

Tie the pencil to the end of the twine or string. Place the other end of the string in the center of the circle. Move the pencil around in a circular motion, drawing a line on the wall. Since I was making arches instead of circles, I simply only drew half of the circle onto the wall, creating an arch.

Using a Purdy mini roller to paint the design on the wall

Step 3: Use a mini roller and paint brush to paint each section of the design

A mini roller is a good size for this design. It allows you to cover the area quickly but it isn’t so big so that you accidentally go outside of your design lines. The mini roller fits perfectly into the Purdy pail, which also holds your paint brush.

Move from one color to another, allowing enough dry time in between colors to avoid any issues where the colors meet.

Putting on a second coat of paint using a Purdy mini roller

Step 4: Apply a second coat of paint to your design

Most of the time paint needs a second coat to make it cover perfectly. I applied a second coat, which fixed any areas I might not have gotten full coverage on the first time.
