I couldn't have jump started it...not that I was even thinking that clearly...but because we didn't have the battery hooked up. I was pleased with myself for thinking of putting it in gear, even though it popped out.
I still see no color on the tags...but if I had to guess I'd say black. It would match the grease.
Not planning a full brake job yet...maybe a new master cylinder...although this one does not look that old. The bleeding can't be that bad....can it? gulp.
