Only using colour to indicate whether a status message is a "for your information", "this looks suspicious" and "this is not OK at all" is a bad idea.
An internal tool we use does green/yellow/red for status messages. It's annoying, even though I'm not at all colour-blind.
@liw Who does that? It's very much not accessible.
@liw I use eink devices so I can receive messages clearly in brightly lit areas, avoid headaches, and work more efficiently... color interfaces are impossible there. And annoying everywhere else.
