What factors contribute to light quality?

1. Color, shape, and surface texture

2. Contrast, reflected glare, and color

3. Temperature, lumens, and aesthetic appeal

4. Shadowing, insulation, and design style

The correct answer is: Contrast, reflected glare, and color

Light quality encompasses several important factors that influence how light interacts with surfaces and affects perception in a space. Contrast, reflected glare, and color are critical components of light quality. Contrast refers to the difference in light levels between various elements in a space, impacting the visibility and emphasis of certain features. Proper contrast can enhance the visibility of the objects and spaces within the environment, making them easier to navigate and visually appealing. Reflected glare occurs when light bounces off surfaces, such as glass or polished floors, creating uncomfortable brightness or distraction. This phenomenon affects the overall comfort of users in a space, making it essential to manage reflected glare for optimal visual conditions. Color relates to how surfaces absorb and reflect light, influencing the mood and visual quality of a space. Different colors can affect the perception of light, making a space feel warmer or cooler based on how they interact with the light source. In contrast to the other options, which incorporate factors that are less directly related to the quality of light, the emphasis on contrast, reflected glare, and color in this choice directly addresses the primary elements that shape our experience of light in interior environments.
