FAQs About NR145 Colorimeter

Because color perception depends on the following factors: 

Light source - For example, incandescent lamps emit orange light, while fluorescent lamps emit cool white light. Therefore, placing an object near different light sources will result in different perceived colors. 

Observed object - Different types of objects affect color perception differently. Examples include opaque objects, translucent objects, and transparent objects. 

Observer's position - Each observer will describe colors differently based on the position of their eyes. 

Different backgrounds - An object's color will appear duller against a light-colored background than against a dark-colored background. Different directions of light reflection from the object - Light reflected from different directions creates different color perceptions. This is particularly noticeable with metallic objects.

Different directions of light reflection from the object - Light reflected from different directions creates different color perceptions. This is particularly noticeable with metallic objects.
