Objective By analyzing the common color naming ability of children aged 2 to 6 in Hunan Province

we can know the general rules of color naming ability in children of different ages and genders

and provide reference for the color naming cognitive screening and rehabilitation education of special children. Method According to the principle of stratified cluster sampling in September 2020

1276 children aged 2～6 in Hunan were tested with the help of the picture naming and color naming test module of ICF-Dr.BrainTM-1

and the difference between age and gender was compared using multivariate analysis of variance. Results 1) There were significant differences in color naming scores among children of different ages（P<0.01）

but there is no significant difference in gender（P>0.05）

and there is no interaction effect between age and gender（P>0.05）; 2) The number of color naming in children of different ages has the rule of age development

and the percentile P10 and P75 were used as the cut-off points for screening stunted and normal children of different ages. 3) The color naming order of children of different ages also has the characteristics of age development

and the research shows that basic color is easy to learn

but mixed color is difficult to master. Conclusion The results show that there are significant age differences in the development of color naming ability of children aged 2 to 6 years

and there is a general acquisition order. It provides an important reference standard for the early screening of special children such as the hearingimpaired with color naming developmental delays

and it also has important application value in the rehabilitation education activities of special children with color cognitive impairment.
