Does the CRI of a shadowless lamp show the color of organize perfectly?


Actually CRI is not a perfect indicator of color quality, as it has some limitations and criticisms.

  1. CRI only uses eight color samples, which are mostly pastel colors and do not represent the full range of colors in the real world. Some light sources may have high CRI values for these samples, but low CRI values for other colors, such as saturated or skin tones. To address this issue, some additional color samples have been added to the CRI calculation, such as the R9 sample for red colors in Mingtai shadowless lamp and the R15 sample for skin tones. However, these samples are not widely used or reported by manufacturers.
  2. CRI does not account for the color preference or adaptation of human vision. Some light sources may have low CRI values, but still produce pleasing or preferred colors for certain applications or environments. For example, some people may prefer warmer or cooler colors than the reference light source, or may adjust their perception of colors based on the context or the surroundings. CRI does not reflect these subjective factors, and may not correlate well with the color satisfaction or acceptance of users.
  3. CRI does not consider the brightness or the color temperature of the light source, which can also affect the color appearance and perception. Some light sources may have high CRI values, but still produce dim or harsh colors for certain situations or tasks. For example, some LED lights may have high CRI values, but low luminous efficacy or high correlated color temperature, which can reduce the visibility or comfort of users. CRI does not capture these aspects, and may not correlate well with the color performance or functionality of the light source.
