The current webui implementation of the logging view is AWESOME. I don't know how easy or hard it is right now, but perhaps there is some kind of web plugin that we can use to "colorize" the log. For blogs and showing code you have things like GeSHi (http://qbnz.com/highlighter/) and I'm wondering if maybe something like that would be able to be incorporated some day. For OpenShift "go" messages we might want to have a syntax highlighting scheme, and this might be usable in the system logs as well (journalctl)...
Since this is an RFE and not a bug, moving this to github so we can have a technical discussion on it https://github.com/openshift/origin/issues/5453
