Color index
a publication of the Society of Dyers and Colorists and the American Association of Textile Chemists and Colorists, containing an extensive list of dyes and dye intermediates. Each chemically distinct compound is identified by a specific number, the CI number, avoiding the confusion of trivial names used for dyes in the dye industry. The Royal Horticultural Society, London, produces a similar document to aid in the identification of flower colors.

production index
a method of expressing production compared with a potential or target.
refractive index
the refractive power of a medium compared with that of air (assumed to be 1).
therapeutic index
originally, the ratio of the maximum tolerated dose to the minimum curative dose; now defined as the ratio of the median lethal dose (LD50) to the median effective dose (ED50). It is used in assessing the safety of a drug.

Subsequently, ten random of petals were selected from each group in three developmental stages to measure the color indices - the color parameter lightness (L*) and red/green (a*) by a TC-P2A colorimeter (Beijing Optical Instrument Factory, China), and each petal were measured in the middle part to reduce errors.
