Painting with Gouache En Plein Air with Bernard Dellario

Introduction to Gouache Painting

Gouache painting is an exciting medium that combines the best of both worlds: the opacity of acrylics and the fluidity of watercolors. In the above episode of Art School Live, we’re diving deep into the art of gouache, particularly focusing on how to effectively use it for plein air painting. Whether you’re a seasoned artist or just starting out, gouache can offer a fresh perspective and a new way to capture the beauty of the outdoors.

Getting to Know Gouache

Gouache is unique in its ability to provide vibrant colors while being easily re-wettable. This means that if you make a mistake, you can simply add a bit of water and work it back into your painting. Many artists are drawn to gouache for its versatility, especially when it comes to plein air painting.

Essential Supplies for Gouache Painting

Before getting started, let’s go through the essential supplies you’ll need for gouache painting. Bernard Dellario, an experienced gouache artist, shared some valuable insights into his preferred materials.

Paint: A limited palette of four colors plus white is sufficient. Bernard recommends using high-quality brands like Himi or Windsor Newton.
Brushes: Synthetic watercolor brushes are ideal. Bernard prefers flats and rounds for their versatility.
Palette: A simple paper palette works well for mixing colors. Bernard also uses a homemade gatorboard portfolio for easy transport.
Water Cup: A bulldog clip with a cup holder can be a handy tool for holding your water cup while painting.

Gouache Techniques for Plein Air Painting

When painting outdoors, there are a few techniques and strategies that can help you get the most out of your gouache experience. Here are some key points to consider:

1. Working with a Limited Palette

Using a limited palette encourages color mixing and helps create a harmonious painting. Bernard emphasizes that knowing how to mix colors is crucial for achieving the desired results.

2. Understanding Gouache’s Drying Properties

One of the challenges of gouache is its drying behavior. Dark colors tend to dry lighter, while light colors dry darker. This can be frustrating, especially for those new to the medium, but it’s essential to keep this in mind while painting.

3. Layering Techniques

Gouache can be layered similarly to watercolor, but with a twist. Once a layer is dry, you need to be careful when applying additional paint, as it can reactivate the underlying layers. Bernard suggests using a delicate touch and allowing the paint to sit on the surface.

Setting Up for Success in the Field

Setting up your workspace efficiently can make a world of difference when painting en plein air. Here are some tips shared by Bernard:

Find a Comfortable Position: Whether sitting or standing, make sure you are comfortable to avoid distractions while painting.
Seek Shade: If it’s a hot day, finding shade can help prevent your paints from drying too quickly.
Use a Spritzer Bottle: A spritzer can keep your paint moist and workable, especially in warmer conditions.

Common Challenges in Plein Air Painting

Painting outdoors presents unique challenges that every artist faces. Bernard shared some of his experiences and how to overcome them:

Dealing with Changing Light

The light can change rapidly outdoors, affecting how you perceive colors and values. Bernard recommends working quickly and focusing on capturing the essence of the scene rather than getting bogged down in details.

Choosing Your Subject

With so many stunning landscapes, it can be overwhelming to choose what to paint. Bernard advises narrowing your focus to a specific element or composition that captures your interest.

Tips for Beginners

If you’re new to gouache, here are some practical tips to help you get started:

Practice Regularly: The more you paint, the more comfortable you’ll become with the medium.
Don’t Be Afraid to Experiment: Try different techniques and approaches to find what works best for you.
Keep a Sketchbook: A sketchbook can be a great way to experiment with ideas and techniques without the pressure of creating a finished piece.

Conclusion

Gouache painting en plein air is a rewarding and enjoyable experience that allows artists to capture the beauty of nature in vibrant colors. With the right supplies, techniques, and a little practice, anyone can develop their skills in this versatile medium. So grab your gouache, head outdoors, and start painting!
