Step-by-step painting guide

Tropical Island

A step-by-step painting guide by Richard Robinson

As we embark on this tropical island painting journey, we'll transform a 14-inch square linen canvas into a vibrant paradise using a palette of Phthalo blue, brilliant magenta, phthalo yellow light, and titanium white. With the help of a gloss medium varnish and a trusty bucket of water for brush cleaning, we'll dive into an easy five-step process that captures the essence of a serene island retreat. This chapter will guide you through creating a dynamic design that balances dark and light areas, ensuring a slightly lighter composition to avoid splitting the scene. We'll breathe life into the island with additional trees, giving it an aged, timeless feel, and add a charming bungalow to evoke relaxation and enjoyment. You'll learn to craft swishy clouds in just two steps and create inviting tropical waters that beckon you to dive in. The palm trees will sway with life, and I'll guide you through each step, allowing you to explore and incorporate these elements into your own work. Together, we'll keep moving forward, opening new doors, and embracing the curiosity that leads us down new artistic paths.

Step 7Caustic lighting effect

Step 7 — Caustic lighting effect (video frame from the lesson)

Add Rock Highlights

Add a slight color change to the tops of the rocks if the paint is still wet. This subtle adjustment enhances the appearance of rocks under the water. Soften all edges for a natural look.

Understand Caustic Lighting

Caustic lighting is the reflected and refracted light on the ocean floor caused by the water's lensing effect. It creates a beautiful effect, often seen as wriggly oval shapes pointing toward the vanishing point on the horizon.

Paint Caustic Lighting

Mix white with a touch of blue and use a dagger or liner brush to paint the caustic lighting. Ensure the lines are wriggly and not straight, pointing toward the vanishing point. As they approach the beach, make them closer together and less distinct.

Enhance Light and Shadows

Add more white to intensify the lighter areas, mimicking the lens effect of water. Avoid painting lines straight over rocks; instead, let them end and continue elsewhere. Use a lighter color to enhance the sparkle effect, as acrylics darken when dry.

Darken Rock Shadows

Before the paint dries, darken the shadows of the rocks slightly. This creates the effect of clearer water, making the rocks more visible. Keep all edges soft for a cohesive look.

Pro tipUse a lighter color to intensify highlights, as acrylics tend to darken when they dry.

Summary & key takeaways

Embark on your tropical island painting journey by establishing a thoughtful design concept, balancing light and dark areas to create a captivating composition. Begin with the sky, using a smooth gradient of blues and magentas to set the scene. As you progress, blend soft clouds into the sky, ensuring they appear natural and dynamic.

Move on to the ocean, carefully crafting the transition from deep to shallow waters with a harmonious blend of blues and greens. As you paint the island and beach, focus on contrast to highlight the sandy shores against the darker sky. Incorporate rocks and caustic lighting effects to add depth and realism, enhancing the illusion of clear, tropical waters.

Finally, bring your island to life with palm trees, a charming hut, and subtle details like seagulls and shells. Pay attention to shadows and reflections to maintain consistency in lighting, and use fine brushwork for the finishing touches. Sign your masterpiece with pride, knowing you've captured the essence of a serene tropical paradise.

Points to remember
  • Create a focal point with the highest contrast and sharpest line.
  • Use a lot of paint with acrylics for smooth transitions.
  • Check your brush for clean colors to maintain hue purity.
  • Keep your arm stiff and rotate from the shoulder for straight lines.
  • Use blurred edges to suggest motion in foliage.
  • Position shadows to the left if the sun is slightly to the right.
  • Use small, thin strokes to mimic subtle reflections in water.
  • Sign your painting in a spot that complements the composition.
