Today I played a type of rules game with the 3-6 year olds

Today I played a type of rules game with the 3-6 year olds where you had to say a color and whoever had this color on their clothes was allowed to pass.

One color mentioned was skin color and I passed and pointed to my shorts which were dark brown. "You're cheating! That's not the right skin color!” the children called after me. (This group only consisted of children with fair skin colour.) Knew that this was a very good opportunity to have a chat about different skin colors and that there are many shades of "proper skin colour". Afterwards, several children were able to pass when the criterion was skin-coloured clothing, and I saw that the children looked at each other's clothes for which shades could be defined as "skin colour"
