Sweethiker, don't be put-off by the responses you've received.
I agree with these guys but I can empathize with you.

I've looked at replacing my mid-height boots with some trail runners but cannot get past the ugly yellow and/or orange accent colors they put on them.

Maybe as TrailRunner says, "Once they're covered in mud it just doesn't matter."
