Painting a cloudy galaxy sky tutorial

Galaxy sky paintings are a beautiful sight to see and even more fun to create. They’re great paintings to practice your “layering,” and paint blending with. A galaxy sky can be a whole painting in itself, or the base of a painting with whatever you’d like like the add to it. Trees, mountains, you name it.

It’s amazing how a black canvas with some colors, and stars added to it can be so magnificent. You can add any colors you desire too!

Today I will be welcoming you to another tutorial, and this one is focused on how I create my cloudy galaxy sky!

For this painting you will need:

-A canvas

-Paint and brushes (black paint and whatever colors you wish for your sky. (White to make stars)

-Newspapers for easy clean up

-A cup of water to clean your brushes in.

-Some paper towels or an old cloth to wipe off your brushes after cleaning

I chose to use a poster board.


Base coat- Black

As I always say before you begin a painting you should add a primer if you like; If you don’t want to use a primer or don’t have any; don’t even worry about it! You’re painting will still be beautiful, I assure you!
My purpose for using black as your base coat is to give your painting a more “somber” background. I use acrylic paint brands (Apple Barrel) and ( Art Deco : crafters acrylic) because they’re not only inexpensive but they’re also very good quaility paint.

When applying your base coat, please be sure to stick with a one way stroke during the application. ( Move your paint brush left to right or up and down.) Choose one stroke and stick to it; this assures your paint will be evenly distributed and won’t have a bumpy texture to it. Giving you a smooth surface for you to blend your paint on.

I would also recommend applying 2 or 3 layers of black paint to your base coat so you know your white canvas definitely cannot be seen through the paint.

Make sure it is completely dry before beginning your actual painting!

You do not want to smudge the base coat and show the white canvas through.

Add some color!

Now that’s your base coat is dry, you can now add yet another layer of black. This is the layer you will be adding your color to while it is still WET.

Once you apply that layer either clean your brush off or switch to a different brush. Also be sure you clean your brush off in between colors.

I primarily used red, blue, purple, and black for some dark clouds; I also added some orange, pink, a lighter shade of blue, and decided not to use grey. Again, you can use any colors you want! Just be sure that your colors are lighter than the sky, but still dark enough to compliment the night sky. I would avoid using white on anything except your stars.

You apply your color in the area desired by gently dabbing your paint brush in circular motions. Start in the middle of where you want them to be bright and move outwards to the edges of where you would like the colorful clouds to stop as you use up all the paint on your brush; before going for another dip of paint. This gives your colorful clouds depth and gives them the look of “near to far away”

You should also try not to over blend your paint. You’re going to want a “blotchy look” for realistic clouds.

I’d like to mention I used not only a “fluffy medium sized brush, but I also used a paint dabber for some bigger, perfectly rounded fluffy clouds.

Every galaxy sky needs some stars.

To give a painting a realistic look and some depth, I like to really layer on my paint. I’ll put a few layers of clouds, overlapping some to show “these clouds are infront of these.”

After a few layers of clouds I would add some Stars on, and then more clouds!

Before you begin adding your stars using the technique I do; I highly recommend laying down a newspaper and going in an area you don’t mind getting painted on! This can be a messy process! So to create some stars with will need white paint. Begin by dipping your brush into the white paint, and lightly brushing off most of it. You only want a small amount of paint on your brush. Too much paint will make stringy globs of paint splattered in your painting; where stars are obviously not stringy and more of a simple “dot” or very small circle. (From far away atleast)

I create the stars by simply taking my brush with the paint, and tapping the middle of that brush onto another brush, and just gently tapping your painted brush onto the middle of the other brush and moving it over your painting putting “stars” wherever you would like. Although it’s hard to tell where they will land with this method of applying.

Thus, the need for the newspaper.  You should be sure to hold the brush at least 4 inchies away from your paintings before tapping it. Being too close can also cause “stringy paint” splatters instead of “dots.”

Here is an example of  “stringy paint splatter”

If you would like you can also individually paint stars by using the smallest/ most thin brush you have and “dotting” them on one by one. I offered my method because it is more efficient for me.

The great thing about acrylic paint is that if you do so happen to make a few mistakes on your stars, you can easily paint over your mistake.

If you would like, you can also add a few shooting stars. If you want to do that, just make sure whatever  paint you have on your brush is completely dry so you don’t smudge your paint. I simply take a ruler, piece of paper or whatever I have nearby with a flat edge, and hold it against the paper, then using a thin paint brush I make a line down using my edge and “viola!” A  shooting star.

I did make a second galaxy sky painting because I was dying to use my new mini easel I made from toothpicks and a hot glue gun.

Just a suggestion; A top gloss coat really brings the beauty out in any sky painting!

Also don’t ever forget to add a signature to your work once it is completely dry. You should ALWAYS claim your art!

Practice makes perfect!

Do not be discouraged if your painting does not come out perfect. I can honestly admit this is far from my best work; I still think it’s pretty.

Sometimes I feel like Picasso when I paint and other days I feel like my 2 year old child could paint better than me. It’s all about picking the proper time and doing it when you’re motivated to!

Do not ever force a painting; it is totally okay to lose motivation and set it aside, then come back to it later. I personally feel that the most beautiful paintings come from the heart; not when they’re forced. I know it can be difficult especially if you have a deadline or simply cannot wait to see the finished product. The key to a good painting really is patience.

Remember a galaxy sky can be a painting in itself, or the base to a painting with any silhouette you desire!
