The color range used in the lighting industry extends from 8,000 Kelvin or 8,000K to 2,000K with 5,000K being the most common. On this scale, the higher the kelvin source value of the light source, the light appears distinctly "colder" and has a color temperature closer to actual sunlight. "Cold" light has a white or blue hue and a color temperature between 4,100K and 6,500K, which is on the higher end of the kelvin scale and includes actual sunlight. Anything that falls above this range will emit light deeper shades of blue andcan exceed the color temperature of sunlight. Additionally, Lights in this range also have shorter wavelengths and are ideal for use in commercial or industrial environments such as parking garages, warehouses, gyms, sports stadiums, outdoor pole lighting, and gas stations. Types of lighting used in these environments include fluorescent, LED, or induction lighting with a color temperature of 5,000K or higher, which has the same or higher color temperature as the sun's temperature. Lights located in the middle of the Kelvin scale, between 3,500K and 4,100K, will have a more neutral white thatresembles a midday light. These lights have mid-range wavelengths and are ideal for use in offices and retail stores. Nevertheless, the "warm" light has anamber, reddish, orange, or soft white to yellow hue and a color temperature of 2,000K to 3,000K, which lies on the lower end of the kelvin scale. This type of light uses longer wavelengths and lamps in this range are commonly used in bathrooms and kitchens [10]. V. C olors in I nterior D esign Color is one of the visual elements which has a great importance due to the energy it carries with a visual content affecting the sensory and mental perception through which a sense of the beauty of the interior design and the integration of its performance, functional and expressive elements is a characteristic of all surfaces. Modern studies of color have greatly influencedinterior design, so the color is no longer in the same traditional concept as a layer of paint or a material for decoration and means of entertainment, but rather color has become one of the material's characteristics and is inseparablefrom it. Moreover, Color is a physical phenomenon, and its main sources arelight and visuals in nature, and it is characterized by three main factors that are interconnected between them. A) Color trait: as it represents the basic colors that are mixed in different proportions giving all other colors. B) Colorvalue: It is the optical value of a color in relation to the extent of its whitenessor darkness, and that is through the degree of reflection of the incident light. C) Color intensity: the degree of purity and concentration of the color characteristic that extends from neutral gray to pure white. However, these factors can be changed by using pigments or by the effect of light falling on them. And far from its visible aspects, color can affect the design elements, their proportions and their relationship. Consequently, the interior design of the spaces requires taking into account the visual effects of color represented by: a) The influences of the form that take into account the aspects related to aesthetics. b) Psychological effects related to aspects of the effects of color onthe human psyche [11]. Table (7.1) shows the analysis of colors.Furthermore, the use of the diversity of colors within the interior spaces is anancient process, as the ancient architects, technicians and craftsmen in different countries were keen to add colors within their buildings in a way that allows for the color diversity and transformation during the day, which depends on natural lighting.
