In a harsh visual world we are living in nowadays, colour is a powerful tool that not only transcends aesthetics and communication but also to evoke emotions, and challenge perceptions. In the 20th century, a revolutionary art movement named Simultanism was established by Sonia and Robert Delaunay, to embrace vivid and bold contrasts to convey dynamic, energy and depth. Simultanism was influenced by the scientific studies of colour contrast by Michel-Eugène Chevreul which suggest that the perception of a colour is altered by the colours surrounding it. This bold departure from the traditional colour theory, somehow, finds a contemporary echo in Colour Clash by Counter-Print UK. This book showcases modern graphic designs where clashing colours are celebrated for their striking visual impact. In both Simultanism and Colour Clash, we witness an ongoing dialogue about the limitless potential of colour. A dialogue that continues to challenge and expand the boundaries of visual expression. 

                   Colour theory tends to rely on specific harmonious relationships to approach visual balance and pleasure. For example, Complementary (Red and green), analogous (Green and Yellow), and triadic (Yellow, Red, Blue). However, Simultanism initiated a different approach by placing contrasting hues next to each other which in return creates tension and a sense of movement that leads to dynamic visual harmony. This method opened new possibilities for how colour could carry different associations and emotions. 

                   In the design realm today, we can clearly see the principles of Simultanism and vibrant expression returning. One of my favourite books – Colour Clash – showcases some of the modern graphic designs that defy conventional colour rules by embracing combinations that were once considered incompatible. Just like Simultanism, designers seem to understand the power of colour and its potential to provoke and captivate beyond its ability to create harmony. The designs in Colour Clash are unapologetically bold, combining colours traditionally taught to clash, yet there they evoke a different feeling. For instance, a design featuring neon pink and deep green demands attention through the visual tension of the contrasting colours. This tension creates a sense of movement and energy, enhancing the overall design as well as making it both more impactful, resonant and memorable. 

                   Based on psychological and neurological principles, our brains are wired to respond to contrast as a survival mechanism which helps us notice and react to differences in our environment. When we encounter unexpected colour pairings, our subconscious is instantly alerted. Consequently, this triggers a range of emotions, from excitement and curiosity to discomfort and intrigue. These responses are powerful because they are visceral, not intellectual, allowing them to create a lasting impression long before we consciously process what we are seeing. When applied to design, the effect forces our minds to work harder to perceive the design, making it more memorable and engaging to the viewer long after the initial encounter. “If you want to dive more into the why, I highly recommend reading Thinking, Fast and Slow" by Daniel Kahneman, and Interaction of Color by Albers, Josef Albers”. 

                   The effect can be seen in the works featured in Colour Clash which I consider a representation of a significant evolution in colour theory. While conventional rules about colour harmony still inform much of design practice, contemporary designers are increasingly willing to experiment with and even subvert these rules. This shift is not just about breaking tradition for its own sake; it is about exploring new ways of engaging audiences in a world where visual overload is the norm. The evolution is relevant in today’s globalised and digitally connected world which means, designers are exposed to a wider range of cultural influences. As a result, the strict associations of colour with specific meanings are becoming more fluid. In this context, the clashing colours seen in Colour Clash reflect a broader trend toward a more inclusive and exploratory approach to design. An approach that values emotional resonance and visual impact over adherence to traditional norms. 

                   In a nutshell, Colour Clash and the legacy of Simultanism remind us that colour is not just a tool for visual harmony, however, it is a language that can be as dynamic, vibrant, and complex as the world itself. By embracing the clash, whether in art, design, or life, we open ourselves to new experiences, methods and the possibility of understanding the world around us. For designers, the lesson is clear: As it is essential to understand the conventional rules of colour theory, it is equally important to know when to break them. The most impactful designs are often those that challenge conventions and push boundaries by using colour to create something truly original and unforgettable. If you have a chance to explore the pages of Colour Clash, consider how these modern designs continue the journey that Simultanism began. Through challenging norms, embracing contrasts and proving that sometimes, the most powerful visuals come from the most unexpected combinations.
