I don't recall them having colorful promos for B&W week the past few years, but if I recall correctly, they did use some colorful bumpers the first year they did this.
My DVR has had a series recording set for the last 5 years for What's My Line? and I've Got a Secret and even while it has been gone, it still has the series set. And every year it still picks up and records the week. I love it.
Very nice promos, I can't wait for the week to start.
