The thesis investigates color/light in the perception and interpretation of space. One understands the presence of space through visual experience. Architectural form is the visual limit which represents mass and its relationship to space. The aim of this project is to develop a color museum where the generator of space is determined by the effects of natural and artificial sources. Finally to experience color action as well as color relatedness in the creation of a form. Color introduces new morphological problems due to these important factors: The color of the building does not depend only on natural resources such as LIGHT generated by the sun, or MATERIAL like wood, stone, and others. Modern technology produces a wide new range of lighting, and materials which are ever changing. Every time we rediscover a new tool, it requires an effort of awareness to understand its use.Today, color is all about us in such vast expression that we take it for granted. Color photography, color television, and modern color reproduction have set new standards for human desires and opportunities. If we could see color for the first time, if we could isolate it from the objects that held it prisoner, then we could open the field of color to achieve clearness in composition, and a greater awareness of the expressions and influence of space. The project: A color liuseun where color light is the expression of the object "space". The program: Three major rooms. One where the characteristics of natural light resources act as the creator of the forms.A second where the use of artificial lights generated the space making, and a third which is the combination of both sources of light combined in one piece.
