Art and science have always been intertwined, but this connection has been reinforced in my recent experience with colour theory, painting, and an extraordinary scientific discovery. What began as sketches of surf rescue boats transformed into a meditation on the nature of colour itself.
From Sketch to Exhibition
My observations at Venus Bay, capturing the interplay between the red inflatable rescue boats and the sea-green illuminated waves, evolved into a series of paintings. The composition fascinated me—horizontal lines of waves contrasted against the strong diagonal of boats running up the surf, foam splashing dramatically in front.
The Olo Discovery
Just weeks after my exhibition acceptance, an announcement emerged from the United States: scientists had discovered a new colour called "Olo." This wasn't just any colour discovery—it represented a new direction in how we understand human vision and colour perception.
I first heard of the discovery on local radio where Professor Ren Ng, originally from Melbourne, was interviewed, revealing something extraordinary. Olo isn't a colour we can see in everyday circumstances. It requires precise adjustments to how our eyes' cones are activated, specifically targeting mid-wavelength cones through sophisticated machinery.
The Science Behind the Sensation
What makes Olo particularly fascinating is its demonstration that colour sensation is essentially an illusion created by energy in the form of visible light of specific wavelengths. The discovery doesn't necessarily suggest colours exist outside the boundaries of the chromaticity diagram, or outside the rainbow as widely reported, but rather reveals new possibilities for how we might experience colour. While we may not see new ways to see a broader range of colours or artificial pigments immediately, the research opens possibilities for enhanced colour experiences, perhaps fixing colour-blindness and a deeper understanding of how our brains process visual information.
The name "Olo" is a little scientific geeky: 010, zero-one-zero representing the signal pattern to different cone types—0 signal to the S cones, 1 or full signal to the M cones, and 0 signal to the L cones. This precision underscores the scientific rigour behind what might otherwise seem like an abstract artistic concept.
Art as Scientific Method
Perhaps most remarkably, this experience demonstrates how artistic practice can parallel scientific inquiry. My methodical approach to colour matching, systematic observation of natural phenomena, and documentation through sketches mirrors the scientific methods in many ways.
The artist's patient observation of colour relationships, light conditions, and natural phenomena provides a different but equally valid path to understanding. When Rob Candy gave me that Wilcox palette, neither of us could have predicted it would lead to connections between 19th-century colour theory, contemporary surf rescue training, and 21st-century vision science.
This convergence reminds us that the boundaries between art and science are often artificial. Both disciplines seek to understand and represent reality, whether through pigment and brush or laser and laboratory equipment. The discovery of Olo proves that there are still new colours to be found—not just in nature, but in the remarkable machinery of human perception itself.
