How to Paint a Lighthouse: Easy Coastal Scene Guide

A lighthouse painting sits at the top of the coastal scene bucket list for most beginners. It looks iconic, it nails that maritime atmosphere, and it is honestly one of the most rewarding subjects to paint because every element reads as dramatic. Big sky. Big ocean. Tall white structure catching the light. It is a painting that looks professional even when you do the beginner version.

Here is the full step by step from people who teach beginner lighthouses regularly along the Queensland and New South Wales coasts. The dramatic sky move, the simple lighthouse structure, and the finishing touches (the light beam, the rocks, the gulls) that turn a simple scene into something genuinely striking.

What you need before you start

Lighthouse scenes need a slightly wider palette than most beginner paintings because you are handling sky, ocean, rocks and architecture all in one canvas. Here is the kit.

Acrylic paints in these colours: Titanium White, Mars Black, Ultramarine Blue, Cerulean Blue, Burnt Sienna, Burnt Umber, Cadmium Red, Yellow Ochre, and Payne's Grey if you have it (or a premixed cool grey). Payne's Grey is brilliant for stormy skies. Our guide on the best paint for paint and sip projects covers acrylics basics.

A canvas in vertical (portrait) orientation. Lighthouses are tall so a portrait canvas is the natural fit. 30cm x 40cm is a solid starting size, 40cm x 50cm if you want more room.

Brushes: a wide flat for the sky and ocean, a medium flat for the lighthouse body (straight edges), a small flat for the details, a fine round for the rails and rocks, and a very fine liner brush for the window details if you have one.

Plus a ruler for the straight vertical lines of the lighthouse, pencil, palette, water, paper towels and an old shirt.

Step 1: Paint a dramatic sky

The sky is what separates a plain lighthouse painting from a dramatic one. Skip the flat blue sky and go for something with atmosphere. A stormy sky, a sunset sky, or a moody grey-and-white cloud sky all work brilliantly and they all use the same technique.

For a stormy sky, load your wide flat brush with Payne's Grey (or Ultramarine Blue mixed with a touch of Mars Black and a touch of Burnt Sienna). Paint the top half of the canvas in horizontal strokes. While still wet, pick up some Titanium White and streak it across in horizontal bands, letting it blend partially with the grey underneath. The partially blended streaks suggest rolling cloud layers.

For a sunset sky, start with Yellow Ochre at the bottom of the sky area, blending up into Cadmium Red and then into a deep purple (Ultramarine Blue plus a touch of magenta) at the top. Use wet on wet blending to keep the transitions soft. A sunset sky behind a dark lighthouse silhouette is one of the most dramatic compositions in beginner painting.

Let the sky dry fully before moving on. About 10 minutes for acrylics.

Step 2: Paint the ocean horizon

The ocean takes up the bottom third of the canvas, below a horizon line positioned around two thirds of the way up.

Use a ruler and pencil to mark the horizon line lightly across the canvas. Two thirds of the way up, dead horizontal. Then mix Ultramarine Blue with a touch of Mars Black for the deep ocean at the horizon, fading down through Cerulean Blue to a lighter blue-white closer to the foreground.

Same three-layer ocean technique as the beach scene tutorial. Deep dark band at the top near the horizon, mid teal middle, lighter shallows at the bottom. Use wet on wet blending to keep the transitions soft. Add a few short horizontal white strokes across the middle of the ocean for wave caps.

Let it dry.

Step 3: Sketch the lighthouse

Use your ruler for this step. Lighthouses are architectural so they need clean straight vertical lines, not freehand wobbles.

Decide where your lighthouse will sit. On the left or right side of the canvas, never dead centre. Positioning matters for composition, off-centre always looks more dynamic.

Sketch the main tower as a tall narrow trapezoid. Wider at the base, narrowing slightly toward the top. The tower should reach from just below the horizon up to roughly two thirds of the sky height. Above the tower, sketch the light room (a small square with a dome or conical roof on top). Below the tower at ground level, sketch a small rocky outcrop where the lighthouse sits.

Optional details: a small door at the base, small evenly-spaced windows up the tower (two or three), a small railing around the top of the tower just below the light room, and a lightning rod or flagpole at the very top.

Keep all your lines light, they will be covered.

Step 4: Paint the lighthouse body

Most lighthouses are white or white with red trim. We will go with the classic look.

Load your medium flat brush with pure Titanium White and paint inside the tower shape, using vertical strokes to build up solid coverage. The flat brush keeps the vertical edges clean. You will almost certainly need two coats over the sky background, let the first coat dry before applying the second.

Now for the iconic red trim. Mix Cadmium Red with a touch of Burnt Sienna on your palette to get a traditional lighthouse red, not fire-engine bright. Using your small flat brush, paint horizontal red bands across the tower. Two or three bands spaced evenly up the tower. The light room at the top also gets painted red (with white dome or roof).

For the rocks at the base, mix Mars Black with Burnt Sienna to get a dark warm grey-brown. Paint the rocky outcrop using short varied strokes to suggest rough irregular rock shapes. Add lighter grey highlights on top of the rocks where imagined light would hit.

Step 5: Add architectural details

This is where you turn a plain white tower into a recognisable lighthouse. Small details, disproportionate impact.

Take your fine brush with Mars Black. Paint the small square windows evenly spaced up the tower, two or three total. Keep them small, real lighthouse windows are narrow. Paint a small arched door at the base of the tower.

Paint the railing around the top of the tower using thin horizontal black lines just below the light room. A line along the top, another line below, and several short vertical strokes connecting them to suggest rail posts.

For the light room itself, paint the windowed section with thin black vertical lines (the panes of glass), and paint a small yellow or white glow inside to suggest the light fixture. The dome or cone roof gets a simple outline in black and a small flagpole or lightning rod at the very peak.

Finally, using your fine brush with a slightly lighter version of your rock colour, add a few highlights to the tower edges on one side to suggest the light hitting the white surface. This subtle shading is what makes the tower look three dimensional rather than flat.

Step 6: The light beam and finishing touches

The most dramatic touch of all. The beam of light sweeping out from the lighthouse.

Take your fine brush with pure Titanium White, thinned slightly with water so it is semi-transparent. Paint a long narrow triangular shape extending out from the light room toward the horizon or the sky. The beam should be wider at the tip and narrower where it meets the light room. Thin soft strokes, not thick opaque ones. You want the beam to look like a glow, not a solid white stripe.

Optional extras. Add a few seagulls to the sky using small curved black M shapes. Add more wave caps to the ocean with small white horizontal strokes. Add a few scattered rocks in the foreground ocean if you want to emphasise the rocky coast. Keep them minimal, the lighthouse and the sky are the stars of the painting.

Stand back from the canvas two metres. The painting should look atmospheric and dramatic, not crowded.

Common mistakes and how to fix them

The lighthouse is not vertical. You freehanded it. Use a ruler and pencil to mark absolute vertical edges, then paint inside those guide lines. If your painted tower already looks slanted, use the medium flat brush to paint straight vertical white strokes along the correct edges, pushing the tower into alignment.

The sky is flat. Dramatic lighthouses need dramatic skies. Flat blue is the beginner trap. Go back and add cloud streaks, a sunset gradient, or a stormy grey layer. Even a five-minute sky rework makes a huge difference.

The light beam looks like a solid stripe. Too much white, too thick. Water down your white until it is semi-transparent, then apply it in thin soft layers. The beam should be a glow, not a wall.

Why we know this works

Paint Juicy runs sessions along the Queensland and New South Wales coasts regularly including regions with actual heritage lighthouses visible from the venue. The lighthouse is a requested subject at coastal sessions and we have refined this exact step by step over years.
