I have some output in my terminal.
When things work I get a green status line, e..g
Using /Users/durrantm/.rvm/gems/ruby-1.9.3-p125 with gemset dmworkflow
I would like to be able to show that in SO in green, which is the way is appear in the terminal.
This would also be useful for manual red/green coloring of passing/failing tests that people would want to colorize to be easier to read.
This is not possible by design.
Allowing too much formatting would quickly detract from the quality and readability of posts. While a case could be made that some cases such as the one you mention might be an improvement, on the whole more people would abuse it than would use it effectively.
If visuals are so important to understanding something, a small pertinent screen shot should be used. If the idea can be communicated using words, better to take a stab at it. Rather than making everybody sort through the screen full of successes for the red failure message, do the filtering for us and just put the error message in the question in the first place.
