Thank you as always for your advice.  
I’m using ConcreteCMS 9.4.7.  
I have a question about the calendar block.  
In “Administrator” → “System and Settings” → “Calendar” → “Color Settings,” there is initially only one color, but when I created a new “topic” by going to “Attributes” → “Topics” → “Add Topic Tree,” it doesn’t appear in “Calendar” → “General Settings” and I can’t select it.  
How can I get this reflected in the topic attributes?  
Thank you in advance.

I figured out how to use it myself through trial and error.  
Thank you.

Could you post a brief explanation on how you did it for anyone else searching for an answer in the future?

I set it up using the following URL as a reference:

>
> concrete5の8.3.0より新しく登場したカレンダー&イベント機能（ブロック？）を使ってカレンダーを作ってみるメモ。

However, I’m not sure which file to edit to customize the time, so I’m asking this question.
