How to Paint a Sunset Over the Ocean: Step by Step

A sunset painting is one of the most universally loved beginner subjects because it delivers maximum drama for minimum technical effort. The colours do all the work. Warm yellow at the horizon, orange and red rising up, deep purple fading into night above. Add a dark silhouette horizon, a flat reflective sea, and you have a gallery-worthy painting in under an hour.

This is not a beach scene tutorial. This is a sunset tutorial. The sky is the entire subject, the sea is just a reflective surface that doubles the colour drama, and the technique is pure wet on wet blending. Here is the full step by step from the Paint Juicy team.

What you need before you start

Sunset palettes are warm and vivid. Mostly yellows, oranges, reds and purples, with a deep dark for the horizon silhouette.

Acrylic paints in these colours: Titanium White, Mars Black, Cadmium Yellow, Cadmium Yellow Deep (or Yellow Ochre), Cadmium Orange, Cadmium Red, Quinacridone Magenta, Dioxazine Purple, and Ultramarine Blue. The deep purple is what bridges the warm sunset colours into the cooler upper sky. Our guide on the best paint for paint and sip projects covers acrylics basics.

A canvas in horizontal (landscape) orientation. Sunsets stretch across the horizon so landscape format is the obvious fit.

Brushes: a wide flat brush for the sky and water (this is the only brush you really need for the main painting), a fine round for the sun and silhouette details. A spray bottle of water is genuinely useful for keeping the wet on wet workable.

Plus pencil, palette, water, paper towels and an old shirt.

Step 1: Mark your horizon line

The horizon line position is the single most important compositional choice in a sunset painting. Get it right and the whole painting feels balanced. Get it wrong and nothing else can save it.

For a sunset over the ocean, position the horizon line slightly above the centre of the canvas, around two thirds of the way up. This gives you more sky (where the colour drama is) and less water (which is mostly a reflection of the sky anyway). Use a ruler and a faint pencil line.

Mark the position of the sun on the horizon line. Off-centre is more dynamic than dead centre. Pick one side and place a small light pencil circle where the sun will sit, partially above and partially below the horizon line as if it is setting.

Step 2: Block in the sky colours from horizon to top

The sunset sky is built from the bottom up, working from the brightest colours at the horizon to the darkest colours at the top of the canvas. The key technique is wet on wet blending in continuous bands.

Start with the area immediately around the sun. Load your wide flat brush with pure Titanium White and paint a small bright halo of pure white around where the sun sits on the horizon. This is the brightest spot in the entire painting, the burning core.

Without cleaning your brush, pick up Cadmium Yellow and paint outward from the white halo, spreading the yellow across the band of sky just above the horizon line. Work fast while everything is wet.

Without cleaning your brush, pick up Cadmium Orange and paint above the yellow band, letting the orange blend into the yellow where they meet. Continue spreading orange across this middle band of sky.

Without cleaning your brush, pick up Cadmium Red mixed with a touch of Quinacridone Magenta. Paint above the orange band, blending into the orange below. The red-magenta band sits in the upper-middle portion of the sky.

Finally, pick up Dioxazine Purple and paint the upper portion of the sky, blending into the magenta below. As you reach the very top of the canvas, mix in a touch of Ultramarine Blue to make the deepest part of the sky shift from purple toward dark blue, suggesting the night sky encroaching.

The result should be a continuous colour gradient from white through yellow, orange, red, magenta, purple, into dark blue at the top. All blended wet on wet in a single session.

Step 3: Soften the bands

Take your wide flat brush, clean and slightly damp (not wet). Gently sweep horizontal strokes across the boundaries between colour bands while everything is still wet. The clean damp brush picks up tiny amounts of pigment and softens the transitions where one colour meets the next.

Do not over-blend. You want to see the colour bands clearly, just with soft transitions rather than hard edges. Three or four light sweeps across each colour boundary is enough.

If the painting is starting to dry while you blend, mist the canvas with your spray bottle (a quick light mist, not a soaking) to extend the working time.

Let the sky dry completely before painting the water. About 10 minutes for acrylics.

Step 4: Paint the reflective ocean

Here is the trick that makes sunset paintings effortless. The ocean below the horizon is just a reflection of the sky above. Use the exact same colours in the exact same vertical order, just slightly muted and with horizontal brush strokes.

Start at the horizon line and work downward. Load your wide flat brush with the same yellow you used for the brightest part of the sky, plus a touch more white to mute it slightly. Paint a horizontal band of yellow along the area immediately below the horizon line. This is the brightest reflection right under where the sun is sitting.

Continue downward with the same colour order as the sky. Yellow, orange, red, magenta. Each band slightly more muted than the sky version (mix in a touch more purple or grey to dull the colours). The sea is darker than the sky because it is reflecting downward and not directly lit.

The bottom of the canvas should be the darkest, deepest tone, mostly purple-blue with hints of red-magenta. Use horizontal brush strokes throughout, never vertical. Horizontal strokes suggest the calm flat surface of water.

While the water is still wet, use a clean damp flat brush to add a few horizontal streaks of slightly lighter colour across the surface. These suggest gentle water ripples catching the sunset light. Keep them subtle, not dramatic.

Step 5: Paint the sun

The sun itself is small but it is the focal point of the entire painting. Get it right.

Take your fine round brush with pure Titanium White. Paint the sun as a small solid circle sitting on the horizon line, partially above and partially below (suggesting it is in the act of setting). The sun should be bright pure white at the centre, not yellow. Real setting suns appear white-hot at their core.

Around the white core, blend a soft yellow halo using the same yellow as the brightest sky band. The halo should be faint and only a slightly larger ring than the sun itself.

Below the sun on the water, add the sun reflection as a thin vertical strip of pure white extending from the bottom of the sun straight down toward the foreground of the canvas. The reflection narrows toward the foreground and becomes broken into small horizontal segments suggesting water ripples breaking up the reflection. This vertical sun-track is one of the most evocative details in any sunset painting.

Step 6: Add a silhouette horizon and finishing details

The painting needs a small dark silhouette element to anchor the foreground and give the eye something to land on. Without it, the painting feels unmoored.

Options for the silhouette:

• A row of small island silhouettes along the horizon line using pure Mars Black with your fine brush. Keep them small and varied in shape.
• A single sailboat silhouette in the middle distance. A small triangular sail with a thin line for the mast and hull.
• A flock of birds across the sunset sky. A few small black M-shapes scattered in the brightest part of the sky.
• A palm tree silhouette in the foreground curving in from one side. The classic tropical sunset addition.

Pick one or two of these. Do not add all of them. Less is more in sunset paintings, the colours should be the star.

Stand back from the canvas about two metres. The sunset should feel atmospheric and balanced. If anything looks unfinished, add one small detail. If it looks complete, leave it alone.

Common mistakes and how to fix them

The colour bands are too distinct. You did not blend the boundaries enough. Wait for everything to dry, then use a dry brush with a small amount of the next colour up the gradient to softly bridge the bands. Soft transitions are what make sunsets glow.

The water looks like a different scene. You painted the water in colours that did not match the sky. The water should be a muted version of the same colours, in the same vertical order, just darker. Repaint the water using your sky colours plus a little extra purple to dull them slightly.

The sun looks yellow. Pure setting suns appear white-hot at the very core. Yellow suns look cartoonish. Fix by repainting the centre of the sun with pure titanium white and only fading to yellow at the edges.

Why we know this works

Sunset paintings are perennial favourites across Paint Juicy coastal sessions in Queensland, New South Wales and the Northern Territory. The wet on wet sky blend is genuinely one of the most satisfying techniques in beginner painting and a common entry point for first-timers.
