No colorized output when using docker with tty: true

[ar-siddiqui]

Using the following configuration in the docker setup and no colors are being printed. Running the application without docker prints color fine.
Docker compose has tty enabled.

	e.Use(middleware.LoggerWithConfig(middleware.LoggerConfig{
		Output: e.Logger.Output(),
	}))

If the same application has colors and does not have colors in docker, this is probably not Echo issue. Colors are enabled by this library https://github.com/mattn/go-colorable
