Hi everyone! In this tutorial, I’m going to show you how to do these blue moon nails. Let’s get started.

Tools and materials:

  • Dark blue nail polish
  • Midnight blue nail polish
  • White nail polish
  • Yellow nail polish
  • Brushes
  • Top coat
Applying blue nail polish

1. Apply dark blue nail polishes to the nail

Apply two different shades (a blue and a midnight blue) of dark blue nail polish to the very top of the nail.


2. Blend

Use a thin brush to roughly blend them in to give the appearance of brushstrokes. 

Applying white nail polish

3. Apply white nail polish

Apply a few dots of white nail polish across the middle of the blue polish.


4. Blend

Blend the white nail polish into the blue polish.

Again, you don’t want this to be a seamless blend so there should be brushstrokes as it’s going to be the sky and sea.

Adding more blue polish

5. Add more blue nail polish

Add more of both shades of blue nail polish to finish off the bottom of the nail.

I also added a purple-blue at the bottom, but it gets lost in it all. Blend it all together, then cure.


6. Continue painting the nail until you’re satisfied 

Go over the nail with a second layer of polishes and add color where necessary, keeping in mind where you want the sea and the horizon to start.

Repeat until you’re satisfied with the background, curing between each layer.


Some things I did include using a lot more white where I wanted the glow of the moon to appear.


I also used black nail polish to draw out the horizon line and faded it down a bit.

Painting the moon

7. Paint the moon

Use white nail polish to draw out the moon. Don’t add too much polish to the brush since you want it to look sheer.

Adding detail

8. Add detail to the moon

Cure, then go in with both the blue and the white to add more patches and detail to the moon.

Adding yellow nail polish

9. Add yellow polish to the moon

I mixed a few different colors to get this pale yellow polish and I went over the moon with it. 

Adding yellow nail polish

Halfway through, I added isopropyl alcohol to water it down a bit to push away the color so we can see more of the detail we added previously.

Adding reflection

10. Add the reflection on the water with white polish

Use white polish to dry brush the reflection of the moon on the water. Pop some lines on and swipe back and forth quite firmly.

Adding reflection

Just keep going until you’re satisfied. The lines shouldn’t get too thick since you’re brushing them.

Adding reflection

You can also go in with some yellow and blue until it looks like rippling water in the moonlight.

Adding clouds

11. Add clouds with white polish

Use white polish to add clouds around the moon. Don’t put a lot of product on the brush. Instead, pat it on and spread it out.

Adding stars

12. Add stars

Add stars with tiny white dots.

Applying a top coat

13. Apply a top coat

Apply a top coat after curing.
