The thesis aims to familiarize us with colors, the influence they have on our brain, and how they can, with proper use, change the feel of any space.The work is divided into two stages. The first consists of 5 color rooms (red, yellow, blue, black, and white) and its purpose is to see how each person reacts to extensive use of a single color. The second stage is a mobile app where the viewer will create their own color combinations and see how different colors can change our perception of space.The presentation of the work will be done with an augmented reality (AR) application. The space of the Yali Mosque has been given for the presentation from July 6-8, 2022.
