광원의 연색성이란 무엇인가요?

The color rendering of light source refers to the degree to which the light source presents the natural primary color of the object. That is, the degree of color fidelity, usually called "color rendering index" (RA). Color rendering is divided into two categories: faithful color rendering and effect color rendering. What we usually call faithful color rendering.

CIE defines the color rendering index of sunlight as 100, and specifies 15 test colors. R1-R15 is used to represent the display index of these 15 colors. When comparing a light source with a specified reference light source, an exponential value of 100 is the best.
