Flower Color Diversity of Ceiba speciosa and C. insignis in Guangzhou

Color science is used to study the flower color diversity of Ceiba speciosa and C. insignis, aiming to provide references for flower color classification methods and materials for the cultivation of new excellent varieties. First, the Royal Horticultural Society Colour Chart (RHSCC) was used to calibrate the flower color. Secondly, multiple color systems (Munsell color system and ISCC-NBS Method of designating colors) were adopted for grading and valuation. Finally, the system clustering method was used for color classification. The results show that the color of C. insignis is divided into 4 groups (purple pink, purple red, light purple pink, yellow white), and the color of C. speciosa is divided into 3 groups (purplish pink, reddish purple, purplish red). The color classification method in this study can successfully classify the colors of C. speciosa and C. insignis.
