Language can be a useful tool for social robots as part of their repertoire of social engagement. This late breaking report outlines preliminary studies into how a child can teach a robot lexicons for colors and color relations. The robot used is a minimal social robot, made from cardboard and foam, that interacts with the children through a simple color naming game. Distributed, non-parametric lexicons similar to those used in previous language learning robot studies are used to store links between words and colors. We visually present the resulting lexicons and highlight the issues that have arisen from this preliminary study and how they can be resolved for future studies. The results of this study indicate that children can teach a social robot lexicons, allowing the children and robot to develop a shared set of symbols for color.
