In this illuminating episode, Xander is joined by Karen Haller, leading expert in behavioural design and applied colour psychology, and author of The Little Book of Colour. Together, they explore how colour goes far beyond decoration—shaping our behaviour, influencing our emotions, and reconnecting us with our true nature.
Karen opens up about her journey from a corporate career to discovering her passion for colour as a powerful tool for change. She unpacks the science behind how colour impacts our physiology and psychology, how our preferences are rooted in memory, culture, and identity—and why bland, neutral design is often more draining than calming.
From the myth of ‘calming’ greys to the importance of designing for behaviour first, Karen shares practical and deeply human insights into how colour can transform our lives—at home, at work, and in the spaces we inhabit daily.
Karen Haller is the leading global authority in behavioural colour and design psychology. She helps brands, designers, and businesses use colour and design strategically to influence behaviour, drive engagement, and support commercial success.
With over 20 years of experience, her work is grounded in human behaviour and nature’s design principles, focusing on how colour impacts the way we feel, interact, and make decisions.
She consults, teaches, and speaks internationally, and is the author of The Little Book of Colour, which has been translated into 14 languages and brings colour psychology to a global audience in an accessible and practical way.
Karen’s approach combines scientific insight with real-world application, helping clients bring their ideas to life with clarity, purpose, and measurable results.
