Temporal and demographic influences on floral colour preferences in urban landscapes: a free-combination experiment

Source abstract

Urban plant landscapes shape public aesthetic experience and colour preferences, yet existing research relies heavily on image-based or lab studies, lacking real-world validation. This study investigates demographic differences and temporal changes in floral colour preference through a field experiment where 57 participants created flower combinations under controlled conditions, with a follow-up after six months. Results showed 68% initially preferred red and pink, indicating a strong inclination towards warm colours. Significant variations occurred across gender, age, and education (p < .05), accompanied by an exclusivity effect between warm and cool hues. Notably, 26% of participants shifted preference from warm to cool tones over time, underscoring the dynamic nature of colour choice. These findings offer practical insights for human-centred planting design that adapts to diverse and evolving public preferences in urban green spaces.
