Colorful Ocean Life in Gouache: Step-by-Step Inspiration

Gouache is a fantastic medium for bold, vibrant artwork, and painting an underwater landscape with it can be a meditative and creatively rewarding experience.

This video tutorial takes you through a playful and imaginative interpretation of ocean life, using bright colors, expressive brushstrokes, and eye-catching details.

Whether you’re an experienced artist or a beginner exploring gouache for the first time, this tutorial offers inspiration and guidance to help you create your own magical seascape.

Why Choose Gouache for Underwater Art?

Gouache is a favorite among illustrators and designers because of its opaque coverage, smooth layering, and bold color payoff.

It’s especially great for underwater scenes because it allows you to easily build up colorful layers that mimic light, movement, and depth—all essential elements when painting marine life.

Its quick-drying nature and re-wettable formula give you the flexibility to make adjustments or layer delicate details like bubbles, coral textures, or seahorse outlines without overworking the paper.

Creating Depth and Flow

The key to a captivating underwater landscape is creating a sense of depth. This tutorial demonstrates how to build layers from background to foreground, starting with wide swaths of cool blues and layering warmer colors over the top for contrast.

The result is a lively sense of movement that simulates the flow of water and the floating dance of seaweed and marine creatures. Using patterns and curved lines, the painting captures a rhythmic quality that mimics how the ocean moves.

Composition and Imagination

One of the highlights of this gouache tutorial is the emphasis on creative freedom. The painting isn’t a photorealistic rendering of the sea—it’s a stylized celebration of marine beauty.

Elements like the bright yellow seahorse, glowing jellyfish, and coral in pinks and oranges are designed for visual interest rather than realism.

This artistic license gives you the freedom to have fun with shapes, lines, and color palettes. The video encourages experimentation with whimsical patterns and even invented plant forms, making this project feel more like play than work.

Tips for Color and Texture

Throughout the tutorial, you’ll find tips on how to balance bold colors without overwhelming your design. Layering is key—letting darker tones dry before applying brighter highlights helps maintain clarity and dimension.

The instructor also explains how to create texture using small dabs and dotting techniques, which work especially well for coral and ocean-floor patterns. Combining fine line work with bold blocks of color helps keep the composition dynamic and visually interesting.

Choosing the Right Tools

The right materials can make a big difference. The video suggests using high-quality gouache paint for more vibrant color payoff and thicker watercolor paper that can handle the water load. A round brush and a fine liner brush are enough to achieve both broad strokes and intricate details.

You'll also notice how using a limited palette can bring harmony to the composition. Instead of reaching for every color in the box, choosing a few complementary hues can keep your underwater world feeling cohesive and expressive.

A Therapeutic Creative Practice

Beyond technical instruction, this tutorial serves as a gentle reminder of the therapeutic power of art. Painting an underwater landscape invites a sense of calm and curiosity. Watching sea creatures take shape under your brush is an exercise in both imagination and mindfulness.

You don’t have to aim for perfection—this project is all about enjoying the process and letting creativity lead the way.

If you’re looking for a peaceful way to spend an afternoon or hoping to add something colorful and unique to your sketchbook, painting an underwater landscape with gouache is a perfect choice. Let the colors flow, and let your seahorses, jellyfish, and coral gardens come to life on the page.
