Colour for behavioural success
Birgitta Dresp-Langley, Adam Reeves

TL;DR
This paper explores how colour information influences behavioural success across species, emphasizing its role in evolution, perception, and practical applications like image-guided surgery, demonstrating that local colour cues enhance task precision.
Contribution
It provides a comprehensive overview of colour's functional role in behaviour and introduces new evidence on how local colour cues improve surgical training performance.
Findings
Colour cues facilitate rapid improvement in surgical precision.
Local colour cues guide attention and improve task accuracy.
Colour-based figure-ground segregation benefits long-term performance.
Abstract
Colour information not only helps sustain the survival of animal species by guiding sexual selection and foraging behaviour, but also is an important factor in the cultural and technological development of our own species. This is illustrated by examples from the visual arts and from state-of-the-art imaging technology, where the strategic use of colour has become a powerful tool for guiding the planning and execution of interventional procedures. The functional role of colour information in terms of its potential benefits to behavioural success across the species is addressed in the introduction here to clarify why colour perception may have evolved to generate behavioural success. It is argued that evolutionary and environmental pressures influence not only colour trait production in the different species, but also their ability to process and exploit colour information for…
