Currently there is not way to disable colorerin logger middleware

I'd also prefer to be able to disable coloring of output, so a PR would be welcome. Colored log output is nice for the developer but usually not need in production (we are gathering logs to a central server, so coloring is more of a pain than helpful).

In that case I would remove coloring altogether. Adding another boolean or something like that would make just API more complex.

In my personal opinion - coloring of output is nice (cool effect) for demoing application startup and has little or no value for actual production environment.

most of the time I start Echo with echo.HideBanner and echo.HidePort and have custom statement to log version+address/port separately. so log rows end up in journald and other destinations in structured format (i'm using zerolog) and same for access log.

Seems like we have exactly the same issues with coloring in logging. And I take the exact same actions. So I'm actually in favor of removing coloring too.

Maybe @pafuent and @vishr or other can show their opinion and others can 👍🏼 (to remove coloring) or 👎🏼 (to keep coloring) in the above post by @aldas .

Logging is overhauled with v5 with no colored output, so we can probably close this issue when we release v5.
