The European research CASTLE (Cabin System Design Towards Passenger Wellbeing) puts the
passenger's perception of well-being at the center of a prototype commercial aeronautics project.
From this point of view, the evaluation of ergonomics and the travel experience become the
objectives of an analysis of the space/context in which color, integrated with the functional
components, of the shape and materials, becomes a tool for the concept design of the cabin space.
The methodological approach developed therefore entrusts color to a primary role in defining the
state of well-being and identity of the cabin space, through a "color model" that can be scaled in
relation to the colors that each company will choose for its own color image
