We've talked before about using color as a beacon when you're in the middle of a crowd. We got two great examples of this technique over the weekend in outdoor events.
First, Michigan governor Jennifer Granholm running in a road race (the video is a little dark at the start - skip to 0:35):
She wears the same tshirt as the rest of the group, with the race logo on it, but while theirs are burgundy, hers is white. This helps her stand out from the others - although her distinctive blond hair helps too.
We get an even better example from Linda McMahon in a Labor Day parade:
In the middle of a sea of supporters wearing navy blue shirts with her logo on them, the candidate wears a bright green blazer. Not only do we see her right away, there's no question who the leader is here. It's a powerful visual.
