3 Ideas for Building LEGO Rainbows

This post may contain affiliate links. Here is our disclosure statement.

Since today is St. Patricks Day, I figure you guys might want to get some inspiration to build yourself some LEGO rainbows! With LEGO bricks coming in about every color under the sun these days, it’s not that hard to do. And once you build your rainbow, you can also build the leprechaun trap that will land you the pot of gold.

What colors do you need for your LEGO rainbow

So before you grab your bricks, you’ll probably need to know what colors you need for your rainbow. If you’ve never noticed, the colors of a rainbow are always in a specific order. I don’t even have to look it up, because The Little Brick has them memorized… and therefore, so do we. From top to bottom:

  • Red
  • Orange
  • Yellow
  • Green
  • Blue
  • Purple

Purple used to be a hard color to come by… especially in any of the Creator boxes. However, there are plenty of boxes these days that include some sort of purple in them:

The one pictured above is the Large LEGO Classic Creator box (10698). However, you can also get a medium box or a small suitcase.

And if you don’t have them, it’s not that much of a big deal. Having most of the colors, as you will see below, is enough to get the message across.

Building styles for your rainbow

There’s many a way you can build your LEGO rainbow, but I think the most common ones are found below:

Stacked brick style

This is probably the way most people imagine a rainbow made out of LEGO bricks. Never fails to get the point across, but let me push your limits with a different technique below.

Flat on a plate

Building flat on a plate is most commonly associated with mosaics. In this case, it can also be useful for building with larger plates. I could see myself adding some clouds around the rainbow if I built it on a plate like this.

Here’s the last style you might want to consider…

SNOT style

No – SNOT is not that green stuff that comes out of your nose. It stands for Studs Not On Top. Basically, it is any method of building with bricks where the studs are facing any direction, except the traditional “top”.

While this was a set for purchase, there’s nothing stopping you from making a similar build. One of my favorite building methods, I can completely see myself creating something of the like.

And in case you still feel stuck, here are several instructions and videos that look promising for building your own LEGO Rainbow:
