Summary

You want to set or update the issue color using Jira Automation

Atlassian is standardizing how we associate parent and child issues across Jira for company-managed and team-managed projects.
This results in deprecation of the Epic Link and Parent Link custom fields in REST APIs and webhooks, as well as in some other related changes.

Environment

• Jira Cloud
• Automation for Jira

Solution

With the correct custom_field, you can build a simple automation to edit the issue color:

You can now use the color names, like blue, green, yellow, etc
