Check out this brilliant green lane:
The vivid green paint is an upgrade for downtown Portland's only coupled east-west bike lanes on SW Oak and SW Stark. The city installed the buffered lanes in 2009, with only green splashes in the lane at intersections, but they seem to be confusing to drivers—often cars will obliviously drive in the lane or use it as a loading zone. In a city survey (pdf) of how the lanes were working, 44 percent of cyclists reported seeing at least one car driving or parked in the lane every week. The city hopes that going all-green will make the lanes' bike-only designation immediately obvious.
