Panel color options via API

[Tim College]

https://community.atlassian.com/t5/Jira-questions/Markdown-for-info-panel-in-Jira-new-issue-view/qaq-p/1183207 - this one has some of the info I'm looking for.

I'm in the midst of migrating to Jira, and trying to get some old notes/color blocks into the Jira "panel" format. It appears that setting the bgColor, as documented here - https://jira.atlassian.com/secure/WikiRendererHelpAction.jspa?section=advanced - is not completely accurate. The panel is normalized to the Warning, Error, Info, and Success types, which is neat.

However, I'm unable to figure out triggering the "Note" type, with a purple background. Everything I've tried gets set to "Info" instead.

Is this not possible?
