Color is an element that has a huge effect on our visual experience. The color reproduction by artificial light sources perform critically importantroles, such as the delivery of information, as well as eliciting interest andinspiration. In the color rendering index (CRI), the color of an object whenseen in natural light is defined as 100. The index then numerically expresseshow close the color of an object seen in artificial lighting matches the colorin natural light. Light sources with a high color rendering index will presentpeople and objects in a clearer and more vivid manner than light sources with alow color rendering index.
