This is the scene near Union Square, inbound, right down the street from the latest the latest MUNI bus vs. cyclist collision.
(Dude got scuffed up by an articulated 38 Geary (or whatever – it’s line number had been switched off) but he looked O.K. when they were putting him the ambulance.)
Anyway, here it is:

Beige? Really? Wasn’t it supposed to be painted green?
(Beige. I think I’ll paint the ceiling beige, after seeing this glorious color up close.)
But, anything for safety’s sake. Hurray!
UPDATE: Turns out, per Bluoz, that this stuff is called “Ride Away/Greenway” or something. It’s from DaVinci Pavement and Design.
And here’s San Francisco Bicycle Coalition Program Director Andy Thornley chirping up to bring it all home:
“It’s actually “fawn” — I brake for Bambi — though others have characterized it as “cafe au lait” or “mochacino” — if it gets people to wake up and pay attention that’s all that matters. It’s another trial for Market Street, joining the forced right turns at 6th & 8th Streets (expect to see 10th Street turns soon) and Art in Storefronts and other good stuff. There’s more to the “Safety Zone” trial, 10 MPH pavement legends and signs, rumble strips, and advance stop lines that will blossom into full-blown bike boxes (with green pavement, you betcha) once the blinking Bike Plan injunction is lifted. These elements (color, rumble strips, 10 MPH marking) will be combined in various ways at the four parts of the 4th & 5th Street intersections (eastbound and westbound), SFMTA and SFCTA folks will be watching and evaluating to see which things are effective at slowing traffic and getting folks to watch out for each other, and then they’ll take the winning combination and implement it at all Market St boarding islands from Castro to the Embarcadero. Get yourself a fresh soy latte and roll on down for a test ride . . .”
So There You Have It.
