[libcamera-devel] [PATCH] libcamera: log: add colors to log levels

[Marian Cichy]

mono-colored wall of logs can be hard to read and doesn't show the level
of failure at a first glance. By adding colors to the log level
categories, it is much easier to scroll through logs and find important
entries.
