What property of form is associated with producing different sensations on the eye due to the way light is reflected or emitted?

The association of form with the sensations produced on the eye due to light reflection or emission primarily relates to color. Color arises from the way light interacts with surfaces, and it is this interaction that creates different visual experiences based on factors such as wavelength, intensity, and the surface properties of materials.

When light hits an object, certain wavelengths are absorbed while others are reflected. The wavelengths that are reflected determine the color that the eye perceives. Thus, color not only plays a pivotal role in aesthetic and artistic contexts but also in practical applications such as influencing mood, ambiance, and even functionality within a space.

Understanding color involves recognizing how it can evoke emotions, highlight architectural features, or impact the perceived size and warmth of a space. In architectural design, the careful selection and manipulation of color can enhance visual dynamics, guide user experiences, and create contrasts or harmonies that are vital to the overall composition of a space.
