-------------------------------------
[~pkarwasz] [~Pavel_K] as much as you were concerned with backwards
compatibility... it slipped through

doing this fixed the issue, but it feels like this was not intended based on
the conversation thread on this ticket...

> Ansi escape code for highlight is generated wrong

> Key: LOG4J2-3537
> URL: https://issues.apache.org/jira/browse/LOG4J2-3537
> Project: Log4j 2
> Issue Type: Bug
> Affects Versions: 2.14.1
> Reporter: Pavel_K
> Priority: Minor
> Fix For: 2.18.0
>
> Attachments: Screenshot from 2022-06-14 16-09-30.png, Screenshot from

> This is a test pattern layout:
> {code:java}
> <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss.SSS}
> %highlight{[%level]}{FATAL=red bright, ERROR=red bright, WARN=yellow bright,
> INFO=magenta bright, DEBUG=green, TRACE=blue bright} [%t] %logger{36} -
> %msg%n" disableAnsi="false"/>
> {code}
> As you see for TRACE level is `blue bright`. However, this is a generated
> code:
> [34;1m[TRACE][m . As you see we have
> [SGR|https://en.wikipedia.org/wiki/ANSI_escape_code#SGR_(Select_Graphic_Rendition)_parameters]
> function with two parameters: 34 is color and 1 is bold.
> For example linux terminal will render it this way:
> !Screenshot from 2022-06-14 16-09-30.png!
> We see, that it is not `bright blue` but `bold blue`. At the same time in
> [manual|https://logging.apache.org/log4j/2.x/manual/layouts.html] they speak
> about different colors:
> !Screenshot from 2022-06-14 16-13-13.png!
> And if we want bright blue, generated escape code should be `[94m[TRACE][m`
> - see the link to SGR function I provided.
