Abstract
In recent years, communication tools are diversified. In particular, around the young, than to communicate to face directly with people, there is a tendency towards the non-face-to-face communication using such as email and SNS is preferred. However, there are many young people who believe that likes to have connected with people. So I considered to propose a tool for interaction to make a connection. Finally, I propose "Iro-kata" to facilitate or assist conversations with color.
