Abstract: The colors of plants can be described using the RHS （Royal Horticultural Society） color chart or measured by a colorimeter based on the CIE （Commission Internationale de I’Eclairage） color space parameters. Due to the differences in principles and measurement processes， there will be significant differences in color descriptions. To compare the differences in flower color description between the RHS color chart method and the CIE colorimeter method， our study compared and analyzed two color description methods for the lilac （Syringa oblata） population with 47 germplasms. The results showed that in the grouping of continuous changing flower colors from violet to purple， the RHS color chart method classified similar flower colors into the purple group， while the colorimeter method classified them into the violet group. The quantitative analysis of the differences between the two methods further revealed that for lilac germplasms from violet to purple， the color parameter values corresponding to the RHS color chart for the flower colors were generally higher and more dispersed in terms of chroma（C*）， a wider hue angle（h）， and a trend of a higher a* value and a lower b* values shifting towards increased redness. This led the RHS color chart method to mostly group the germplasms with continuous changing phenotype from violet to purple into the purple group with more redness， rather than the violet group with blue. The RHS color chart method and the colorimeter method are used for different scenarios due to their respective advantages. The analysis of flower color groups for the lilac germplasm population conducted in this study quantitatively described the methodological differences between the two methods and provided the basic cause of the differences in flower color description between the two methods. It also offered a reference for the evaluation of group flower color and flower color genetic improvement.

摘要： 植物的色彩可用RHS比色卡描述，也可用基于CIE色彩空间参数的色差仪测定。由于原理和测定过程的不同，两种方法会在色彩描述上产生差异。为比较RHS比色卡法与CIE色差仪法对花色描述的差异，本研究针对47份丁香（Syringa oblata）种质的鲜花通过两组实验进行比较分析。结果发现：在蓝紫色至紫色连续变化的花色分组中，RHS比色卡法将更多种质归为紫色组，而色差仪法则将它们归为蓝紫色组。两种方法的差异定量分析进一步表明，对于蓝紫色至紫色的丁香种质，RHS色板对应的花色参数值相比CIE色差仪对鲜花的测量值，总体呈现更高且更为分散的色彩饱和度（C*）、更宽的色相角（h），以及红度值（a*）偏高同时蓝度值（b*）偏低的红向偏移趋势。这使得RHS比色卡法将蓝紫色至紫色连续变化的种质大多归为了带有更多红度的紫色组，而非带有蓝度的蓝紫色组。RHS比色卡法与色差仪法因各自优势而用于不同场景，我们针对丁香种质花色所做的分析，对两类方法的系统性差异进行了定量描述，分析了花色描述的差异根源，为群体花色评价和花色遗传改良提供了参考。
