The beach has been the backdrop of my life. It’s where I was born and raised, played, worked as a lifeguard…and now enjoy summer days with my family. I spend a lot of time learning and practicing capturing the ocean in watercolor.
How to Paint the Ocean with Watercolor and Gouache:
1. Reference photo. I always work from a photo. I have the luxury of taking my own ocean photos, but even if you can’t, there are plenty of photos online to use as reference.
2. Tape your paper to a board. My favorite paper is Fluid watercolor blocks. I use the cardboard back of an old, larger pad and painter’s tape.
3. Tape your horizon line. To ensure a straight line I tape it. I eyeball how much from the photo and measure and mark with pencil both sides of my paper so it’s straight. Put the tape above your marks.
4. Mix your colors. I use ultramarine, cadmium red, and cadmium yellow and mix them to achieve the different shades of the ocean. Since the ocean is many different colors I find this to be the best way to achieve the natural looking colors I’m looking for. The color of the distant ocean is usually bluer, the waves that are closer are greener, and underneath the foam is brown water. Very wet sand reflects the sky and has a bluish tint. As the sand gets further from the ocean (and is drier), it is lighter.
5. The first layer. I paint with a brush, wet with paint, onto dry paper. I start at the horizon with a bluer mix for the distant ocean and switch to a greener mix for closer waves. For the underneath of the foam of the crashing wave I add a little grey (made from my mix of blue, red, and yellow) and light greens. In front of the wave, I use a browner blue mix and closer to the shore, where the foam is, I use a brown mix. The sand closes to the water’s edge is darkest. From there I lighten the brown (make more translucent) with water for the drier sand. I cover most of the paper.
Let your first layer dry. The first layer often looks like a blob – don’t be discouraged! Watercolor is all about building up the layers and nothing is really permanent. You can manipulate and even erase the paint (by touching it with a wet brush and blotting the brush on a paper towel).
6. Adjusting the first layer – If your first layer is a bit washed out, add more paint to darken it. Use your photo as your guide. You can use this time to add darks and lights in the distant ocean, as well as within the wave in the foreground. If your first layer is very dark, you can use a wet brush to pull up some of the paint, to create highlights.
7. The sky. When your ocean at the horizon is completely dry, gently peel up the tape. The simplest way to paint the sky is to start at the top of the painting (I always turn it clockwise to paint the sky). Paint with a brush saturated with cerulean blue at the top of the painting (on your right if you turned it). Test the saturation of cerulean blue on a scrap of paper before touching your painting. Paint a few thick strokes, then dip your brush into your water, and paint another few strokes touching your first one. Paint to horizon line, dipping in water again if needed. You are watering down the paint as you get closer to the horizon line. The sky is lighter at the horizon and more saturated as you look up from there. Read this post if you want to explore painting more complex skies.
8. The foam – White gouache. Add the foam in the break of the wave and closer to the shore with white gouache. Gouache is more opaque than watercolor so you can paint with white over other colors. Use a flat brush and create overlapping horizontal zig zag lines for the foam close to shore. The flat brushes I use are: 1/8″, 1/2″, 3/4″. In the breaking wave use different techniques – with a round brush paint circular strokes, and paint small dots or specks (stippling).
Let this layer dry.
9+. Adding details. Compare your painting to your reference photo. They do not need to be exact! What areas need more detail, highlights, shadows, or color changes, etc.? This can involve several additional layers, with drying time in between, or just one or two. It all depends on the look you are going for – how loose, how realistic.
Details I add:
In the foam: I usually add more shadows (with dark brown or grey) within the foam, and blend it with the gouache, and more white gouache zig zag strokes on top of that.
In the crashing wave: There is a lot of depth in a crashing wave. I usually add shadows on top of the gouache and then add more gouache on top of that. Add little white dots for spray. I sometimes pat my finger on top of these so they look more natural. Depending on my reference photo, I may need to paint on the barrel of the wave (with a mostly dry brush). I usually add darker areas in the water in front of the breaking wave.
Distant ocean: If needed – dark and light areas for forming waves, and moving water.
Dark sand at the ocean’s edge: Right next to the edge of the water add a dark line of brown. Then go back with a wet brush and touch the line to “bleed” the brown.
Add more paint to the wet area if necessary to create more wet sand.
Calling it done! I usually work on a painting on and off for about a week. When I think it is close to being done, I prop it up and look at it from across the room. I may add a few more details. Sometimes it’s better to call it done, because tweaking it, may affect other areas. I’ll remember the “challenges” with a painting and try to overcome them in the next painting.
