Psychology of Colour in User Experience/Interaction: ‘Emotional Colour in Visualisation’ Theory in Interaction Design for User Experience: The Design of the Italian Medical Linkage System as an example

User experience research methods and user-centred design thinking have become dominant in interaction design. Thus, exploring the migration of user experience methods and theories to interaction design practice has become a common goal for designers and researchers. As one of the bridges between emotional design and visual design for interaction, visual emotional colour theory can become one of the dimensions of design standards in immersive user experience research. Therefore, the use of visual emotional colour theory in user-centred interaction design practice is explored in this study from the perspective of colour psychology, in conjunction with the design of Italian medical linkage system.
