How to Draw A Cartoon Rainbow – Let’s get Started!

Step 1how to draw a cartoon rainbow step 1

The picture we will be drawing in this guide on how to draw a cartoon rainbow will be a stylistic one that has each end of the rainbow resting on a cloud.

We will begin this process by drawing the cloud on the left.

As shown in the reference image, the cloud will be drawn using a series of rounded lines connecting to one another to make it look nice and puffy.

There will also be some curved lines inside of the outline to provide some puffiness to the interior.

As you can see in our reference image, we will also leave an empty space on the right-hand side of the cloud, but we will fill that in later.

Step 2 – Draw some more of the cloudhow to draw a cartoon rainbow step 2

We will finish off the outline for the first cloud of this cartoon rainbow drawing in this second step.

The right-hand side of the cloud will be a bit thinner, but it will be drawn with some similarly small, curved lines connecting to one another.

There will also be some curved lines inside of the outline for further puffiness.

That’s all for this cloud, and then we can move on to some more details in the next steps!

Step 3 – Now, draw a second cloudhow to draw a cartoon rainbow step 3

For this step of your picture, we will essentially be recreating everything you did in the first two steps to create a second cloud for the composition.

As you can see in our example, this cloud will be reversed, but it will be a mirror image of the previous one.

That means that it will have the same bumpy outline with the same inner details. You could change up how some of these outlines look if you wish! Then, we can start drawing the rainbow itself.

Step 4 – Star drawing the rainbowhow to draw a cartoon rainbow step 4

As we mentioned in the previous step, this one will be focused on drawing the rainbow itself. To do this, we will essentially be drawing several curved lines stretching from one cloud to another.

The lines we will use for the rainbow will be fairly simple, but it can still be trickier than you may expect!

For that reason, we will be taking it slowly as we draw them. Start by drawing the outer line of the rainbow, and try your best to keep it nice and smooth.

Then, we will draw three more layers of these lines underneath it. That’s all you need to do for now!

In the next few steps, we will be finishing up the drawing with some final details and touches, so let’s proceed when you’re ready!

Step 5 – Now, you can add the final details for this cartoon rainbow

You’re ready to finish the outlines for this cartoon rainbow drawing now as we add the final touches and elements.

First, you will be adding four more curved lines to the inner edge of the rainbow. These will run parallel to the previous ones, and they will get smaller with each one.

Once you have finished these lines, you have completed the design, but you don’t have to stop there!

This is the point of the guide where you can add some extra details of your own.

You could maybe design a beautiful background featuring clouds and birds for one idea, or you could incorporate it into a more stylistic design!

For another fun idea, you could give it an Irish twist and draw a pot of gold under the rainbow! These are just a few ideas, but what else can you think of?

Step 6 – Finish off your drawing with some colorhow to draw a cartoon rainbow step 6

Now it’s time to close off this guide on how to draw a cartoon rainbow with some colors!

If there’s one thing rainbows are known for, it’s their colors, and they are often used as a color benchmark.

Rainbows usually have a specific color scheme in real life, but this is your drawing so you could go for other colors if you prefer.

In our reference image, we created a stunning image by using a different color for each layer.

You could take a similar approach for your own one, or you could change it up and go for some color patterns instead.

We also think that some bright art mediums such as colored pens or markers would look amazing for this drawing.

It’s up to you, so how will you finish off this image with your color creativity?

Rainbows are associated with various myths and legends that you could use for this artwork. One of the most famous ones to use would involve leprechauns.

It would look amazing to use watercolor paints for this purpose, for example!
