Colour reflection occurs naturally in our environment. Surfaces absorb parts of the colour spectrum when a light beam interacts with them and we perceive a coloured surface, but they also reflect portions of their colour onto nearby surfaces. These reflections are influenced by several factors: the type and direction of the light source, the colour and properties of the reflected surface, and the characteristics of the surface receiving the reflection.

In this thesis, I have searched for situations where colour reflections arise and explored how this effect can be consciously created and utilized in spatial contexts. Through material experimentation and spatial testing, the work explores the question: How can the colour reflection effect be controlled, and in what ways can it be used in spatial contexts? 

Through my investigations, I identified the significance of backlighting and shadows as essential conditions for the colour reflection effect to appear. I explored how these conditions can be created both through artificial lighting and daylight. The result is two series of spatial elements: one using artificial light: ceiling panel shades, and another using daylight: vertical blinds. The ceiling panel shades are designed to fit into standard ceiling grid systems found in many public buildings, offering not only visual variation but also aiding in orientation, defining spatial zones, and enhancing spatial dynamics. The vertical blinds respond to changing daylight conditions and contribute to a layered and time-based spatial experience.
