As of T89765: Show warning about privacy/security issues on PDF file pages being resolved we now have an orange warning color available for certain icons.
From the (abandoned, but content-wise valueable) LSG draft:
Warn (orange) conveys to the user their action may fail or have serious consequence but are not destructive. Some examples could be that an edit is likely to encounter an automated block due to the nature of the content, or that a preference is being reset to a default options.
From event management differentiation by ITSM:
Informational events [notices] are typically events within normal operating boundaries. They are the types of “good” events that tend to fill most IT Service Management tools. These events are typically an indication that something has worked as it should.
Warnings are an early indicator or potential indicator of trouble. However, we need to understand that a warning is a flag to something being “unusual”, not necessarily negative (e.g. someone logs in after 6 weeks of inactivity)
Exceptions [errors] are the most typical precursor to incidents, but they will not always lead to an incident (e.g. a CPU spikes above the set threshold as a power user starts a processing job). Exception events will generally be of interest to IT Operations staff as they may be a sign of more trouble to come.
