koi fish painting

The challenge of learning how to paint watercolor is controlling the water and paint.

Challenges are fun that is what makes this watercolor koi painting so enjoyable.

materials

This painting is on an 11x14 Aquabord. The aquabord does not bend. That makes it easy to pick it up and tilt it to move the poured paints where you want them.

  • Transfer your drawing to the painting surface with graphite paper.

  • Mask the highlight areas on the water with masking fluid. Let the masking fluid (also called frisket) dry completely before proceeding.

This watercolor koi fish painting is done with tube watercolors.

  • New Gamboge Yellow
  • Quinacridone Red / Winsor Red
  • Prussian Blue

painting koi fish

Start the painting with yellow koi who is the focal point of the painting.

Painting-watercolor-koi-fish-2Start painting the focal fish.

We bring attention to a focal point by using warm verses cool colors.

We also use contrasting values.

He is painted with New Gamboge. Add a bit of blue to grey down his fins.

The eyes and mouth are a combination of red and blue that makes a black.

Next is the side-kick of the yellow koi fish. This koi is a bit smaller, so it will look deeper in the water.

Painting-watercolor-koi-fish-1The colors flow to make orange.

Paint yellow on what will be the orange parts of the koi fish.

While it was still wet, drop in some Quinacridone Red. They mingled together to create orange.

Lightly used some yellow to indicated warmth on the white areas of the fish.

That's the beauty of painting koi fish with watercolor. The watercolors flow together so beautifully.



Next is the body guard for the yellow koi fish. He looks tough, don't you think?

Painting-watercolor-koi-fish-3Paint the red and black / leave the white dry.

Wet the colored areas of the fish with clear water and leave the white areas dry.

Paint the red areas with Winsor Red. Quinacridone Red didn't give a very bright red. Use whatever red you prefer. The cadmium reds or their replacement (Winsor Red) give the most saturated red colors.

While the red was still wet, add some black spots. The colors softly mingle together. (Mix the red and blue for the black.)

Oh, the beauty of painting watercolor!



We can practice pouring watercolor with this koi fish. (How to pour is in the next section.)

Practice pouring the watercolors on the koi fishExperiment with the top fish.

Pour yellow on one side.

Then pour red on the opposite side of the fish. Let the two colors to mingle together.

They mingled, but they ran outside of the area of the fish because the mix had too much water.

The dark background will cover the runs outside of the fish's body.

That's part of the challenge of pouring with watercolor.

Next - the background

The major painting is done on the koi fish. Let them dry.

Painting-watercolor-koi-fish-5Ready to do the background

We will detail the koi more after the background is finished.

When the background is done, we will be better able to see the colors and values. Then we can use them to our advantage.

pouring watercolor for the background

Pouring is a fun part of painting these watercolor koi.

Use small cups to mix the watercolors and water.Mix the paints in cups with water.

Put about a quarter inch of each color into separate containers. The small cups used for dipping crab in butter work great.

Add about a tablespoon of water.

Stir thoroughly to dissolve all the paint.

start pouring the watercolors

Be sure the fish are dry!

  • Keep the painting support level. We are better able to control the colors and keep them out of the koi on a level surface.

I started with the blue in the upper right. Then I put some red on the left. The top edges of the blue and red were spritzed to make them softly move out into the white.

Keep pouring the three colors around the koi. Use your artistic license and choose what looks good to your preferences.

The unpredictable movement of the colors is a joy of pouring watercolors!

let the paint dry

  • When you are satisfied with the results, let the koi fish painting dry overnight.

The colors between the lower left koi look brown. Oh-oh, I realize what I did. I broke one of my own rules.

I mixed Winsor Red. It is not a transparent color. It doesn't mix well with other colors. So I got brown instead of a purple. But actually it makes a warm background for the warm fish.

The background around the yellow focal fish is cool. The contrast brings attention to the focal koi.

Finish pouring the background around the koi fish.The pouring is finished. Let it dry.

detailing the watercolor koi

Look over each koi. Make any necessary adjustments that catch our eye.

Detailing the koi paintingUse a damp brush to soften the edges of the koi.
Keep the contrast between the focal koi fish and the surrounding water.Leave the hard edges on the focal koi to make him stand out.
Paint shadow color on the edges of the koi fish to give it form.Apply a thin wash of blue around each koi to set them into the water.
Retrieve the fins of the Koi.If the poured watercolor went over the fins, clean them with a stiff damp brush.
  • Make sure the painting is dry, then remove the masking.

When I was first learning how to paint watercolors, I made the mistake of removing masking from damp paint.

What a mess! The masking picked up paint. I got paint on my fingers and touched it into areas where it didn't belong. A lesson well learned.

the final touches

  • Make any corrections that catch our eye.

  • Where the masking was removed from the water swirls, soften them with a damp brush. Shadow the swirls to give them form.
  • The top left fish was competing with the focal fish. So the swirl across its head was removed.
    The contrast with his background was lessened, so he didn't draw so much attention.
    The dark on the right of its body was removed by spritzing water on the color and blotting it up with a paper towel. Red was poured to replace the dark color.

painting koi fish is fun - enjoy!
