メンションの色について（About Mention Color）

[杉戸恵]

新仕様になってから、メンションの方法が少し変わりましたが、色がグレーの時とブルーの時の違いな何でしょうか。メンション自体はできているようです。

Since the new specification, the Mention method has changed a little, but what is the difference when the color is gray or blue? Mention itself seems to be done.

Hi there, 

Welcome to the Atlassian Community! 

While you're still drafting your comment or card description, after you use "@", the text should turn blue while you're in the process of mentioning the right person. The mentioning would work once you pick someone and the tag is displayed on a gray background. 

If that's not what you're experiencing, could I ask you to create a ticket through https://trello.com/contact providing some examples and screenshots? This gives us access to a few more tools to help investigate, and we can discuss information that can't be shared in the community.
