CRI measures on a scale of 0 to 100 how a light source shifts the location of eight specified pastel colors compared to the same colors lit by a reference light source of the same CCT. A CRI of 100, or perfect color rendering, means the light source renders the eight colors exactly how the reference light source renders them.
