In October 2018, seeds of different flower colored Impatiens balsamina were collected in Lin’an, Zhejiang province, and in April 2019 and 2020, seeds were sowed for cultivation. In September and October of the same year, different colored flowers were collected for CIEl AB color scale, and determinations were made on traits of corolla and nutrient organs. The results showed that flowers could be divided into white, pink, red, purple, and reddish purple. Based on CIEL color space, pink, red, purple and reddish purple flower had higher a* values, whereas white one had lower a* values. The b* values of purple flower were lower than that of the others. White and some pink flower had higher L* values and lower C* values. However, red, purple, reddish purple and some pink flower had lower L* values and higher C* values. The corolla diameters were ordered by white and pink, purple, red and reddish purple. There was no great differences of leaf sizes among different colored I. balsamina. The plant height was followed by white and reddish purple, red and purple, pink. The variation analysis on quantitative traits showed that there had large variation among I. balsamina individuals.
