Painting outdoors, known as plein air painting, allows artists to capture the fleeting effects of natural light and atmospheric conditions. We learned this the hard way… However, successfully managing colour harmony in these constantly shifting environments can pose a unique challenge. In this comprehensive guide, we’ll explore durable techniques and strategies to achieve vibrant, harmonious colours when painting landscapes on location.
Mastering Colour Mixing for Plein Air
Colour mixing is a fundamental skill for any plein air painter, allowing you to create a cohesive, harmonious palette from the complex array of hues found in nature. Begin by establishing a limited but versatile colour scheme, choosing a selection of pure, high-chroma pigments that can be mixed to achieve a wide range of natural tones.
Opt for a mix of warm and cool primaries, such as cadmium yellow, alizarin crimson, and ultramarine blue. Supplement these with supporting colours like viridian green, burnt sienna, and titanium white. This focused palette will help you maintain control over your colour relationships, even in the face of shifting outdoor lighting.
When mixing colours on your palette, pay close attention to the relative temperature of each hue. Warmth and coolness are crucial factors in achieving harmony – a judicious balance of warm and cool tones is essential for creating a sense of depth and atmosphere. Experiment with various mixing techniques, from direct mixing to layered glazes, to develop a repertoire of approaches that work best for your style.
Regularly pause to assess the colour harmony of your painting as a whole, stepping back to evaluate the relationships between hues. Make necessary adjustments to double-check that a cohesive, balanced composition. Remember, colour is always relative – what appears harmonious in the studio may shift dramatically outdoors under natural light.
Harnessing the Power of Underpainting
An underpainting can serve as a powerful foundation for achieving harmonious colour in plein air landscapes. By establishing an overall tonal harmony in the initial layers, you can then build up your painting while maintaining a cohesive, integrated palette.
Begin with a toned ground, such as a warm or cool grey, to create a neutral base. This will help unify the subsequent layers and prevent the white of the canvas from creating a disconnected, disjointed appearance. Alternatively, consider an alla prima underpainting using a limited palette of complementary or analogous colours. This can help establish the key colour relationships from the outset, guiding the development of your painting.
As you progress, use the underpainting as a springboard for your subsequent layers. Selectively reveal areas of the underpainting to create atmospheric effects and a sense of depth. Glazing and scumbling techniques can further integrate your top layers with the underlying colours, reinforcing your overall colour harmony.
Remember, the underpainting is not merely a preparatory step – it is an integral part of the painting process, shaping and unifying your entire composition. Experiment with different approaches to find a method that best suits your preferred plein air painting style.
Adapting to Shifting Outdoor Conditions
One of the primary challenges of plein air painting is adapting to the constantly changing natural lighting conditions. As the sun moves through the sky, the quality and intensity of the light can dramatically alter the appearance of your colours, necessitating ongoing adjustments.
Develop a keen observational eye to track these shifts, quickly recognizing when you need to make corrections to your palette. Regularly step back from your easel to assess the overall harmony, making subtle colour adjustments as needed. Be prepared to remix colours on your palette to match the evolving scene.
Additionally, consider incorporating atmospheric effects into your painting to enhance the sense of depth and harmony. Judiciously applying soft, muted edges and atmospheric glazes can help unify your composition and convey the sensation of shifting light.
Mastering the art of alla prima colour mixing is also crucial for plein air painting. Quickly blending and applying pure, expressive brushstrokes can capture the essence of the moment, allowing you to remain responsive to the continually changing environment.
Leveraging the Power of Oil Paint
Oil paint’s inherent properties make it a particularly well-suited medium for achieving harmonious colour in plein air landscapes. The slow drying time of oils allows for extended blending and reworking, enabling you to refine your colour relationships over multiple painting sessions.
Furthermore, the translucent quality of oil paints, when used in glazing techniques, can create a sense of atmospheric depth and unity. Carefully applied layers of transparent colour can subtly unify your composition, harmonizing the relationship between hues.
The versatility of oil paint also allows you to experiment with a range of impasto and textural effects, further enhancing the harmonious interplay of colour and light. Employ techniques like scumbling, dry brushing, and palette knife application to achieve a variety of mark-making that can help integrate your painting.
Consider incorporating mediums and additives to modify the working properties of your oils. Alkyd resins, for example, can speed up drying times, while oil-based varnishes can enhance the vibrancy and protection of your final painting.
Embracing the Unpredictable
One of the joys and challenges of plein air painting is the unpredictable nature of the outdoor environment. Embrace this sense of spontaneity and adaptability as an integral part of your creative process.
Be prepared to make quick, intuitive decisions in response to changing conditions, trusting your colour instincts and making bold, expressive marks. Avoid overthinking your palette or getting bogged down in a search for perfection. Instead, foster a playful, experimental mindset, allowing your paint to dance across the canvas in harmony with the ever-shifting landscape.
Engage all of your senses when painting en plein air, absorbing the sights, sounds, and smells of your surroundings. Allow these sensory experiences to inform and inspire your colour choices, creating a deeper, more authentic connection between your painting and the natural world.
Throughout your plein air journey, embrace the unexpected. Celebrate the happy accidents and serendipitous moments that arise, using them as springboards for further exploration and discovery. By cultivating a spirit of openness and adaptability, you’ll unlock new avenues for achieving vibrant, harmonious colour in your landscape paintings.
By mastering a range of techniques for colour mixing, underpainting, adapting to shifting conditions, and leveraging the properties of oil paint, you’ll be well-equipped to create harmonious, plein air landscape paintings that capture the essence of the natural world. Embrace the challenges and revel in the rewards of painting outdoors, allowing the ever-changing environment to inspire your creative expression.
