委员会建议由一级技术委员会制定一个新的显色指数（或一套新的显色指数）。该指数（或这些指数）不得立即取代当前的CIE显色指数。新索引的使用应提供补充当前CIE CRI的信息，在成功整合新索引后，将考虑替换CRI。新的补充显色指数（或一组补充显色指数）应适用于所有类型的光源，而不仅仅适用于白色LED光源。本技术报告附录中总结了改进显色性描述的可能性。报告用英文写成，并附有法文和德文的简短摘要。它由14页和1个数字组成。

The Committee recommends the development of a new colour rendering index (or a set of new colour rendering indices) by a Division 1 Technical Committee. This index (or these indices) shall not replace the current CIE colour rendering index immediately. The usage of the new index or indices should provide information supplementary to the current CIE CRI, and replacement of CRI will be considered after successful integration of the new index. The new supplementary colour rendering index (or set of supplementary colour rendering indices) should be applicable to all types of light sources and not only to white LED light sources. Possibilities for an improved description of colour rendering are summarized in the Appendix of this Technical Report.The report is written in English, with a short summary in French and German. It consists of 14 pages with 1 figure.
