There is no practical and at the same time objective colour system available for describing cultivated roses ( L. cultivars). For this reason, a new colour classification system was developed which is colorimetrically balanced and appropriate for algorithmic colour identification; however, it is also suitable for field-work. The system is based on the following colorimetric criteria: (A) Each colour category is characterised by a measured petal colour in the CIE Lab* standard as the centroid of the category. (B) The CIEDE2000 colour differences between the adjacent centroid colours are limited (5 < ΔE < 7). (C) The maximal colour difference between the measured colours in a category is also limited (to 12.12 ΔE). (D) A measured petal colour can only be classified into an existing category if the colour difference from the centroid colour of the given category is less than 5.81 ΔE, otherwise a new category is required. (E) A category is only considered non-redundant if it has at least one measured petal colour that cannot be classified elsewhere. (F) The classification of the petal colours is based on the least colour difference from the centroid colours. As a result, 133 colour categories were required for describing all the 8139 petal colours of the rose cultivars of the Budatétény Rose Garden (Hungary). Each colour category has the following parameters: standardised colour name, the colorimetric parameters of the centroid, grouping, RHS colour chart coding, and reference cultivars, which are described in the article.
目前尚无实用且客观的颜色系统可用于描述栽培玫瑰（蔷薇属栽培品种）。因此，开发了一种新的颜色分类系统，该系统在比色上是平衡的，适用于算法颜色识别；然而，它也适用于实地工作。该系统基于以下比色标准：（A）每个颜色类别以CIE Lab*标准中测量的花瓣颜色作为该类别的质心来表征。（B）相邻质心颜色之间的CIEDE2000色差是有限的（5 < ΔE < 7）。（C）一个类别中测量颜色之间的最大色差也是有限的（至12.12 ΔE）。（D）只有当测量的花瓣颜色与给定类别的质心颜色的色差小于5.81 ΔE时，才能将其分类到现有的类别中，否则需要一个新的类别。（E）只有当一个类别至少有一个测量的花瓣颜色不能归类到其他地方时，才认为该类别是非冗余的。（F）花瓣颜色的分类基于与质心颜色的最小色差。结果，描述匈牙利布达泰泰尼玫瑰园玫瑰品种的所有8139个花瓣颜色需要133个颜色类别。每个颜色类别都有以下参数：标准化颜色名称、质心的比色参数、分组、皇家园艺学会颜色图表编码和参考品种，本文对此进行了描述。
