Back in high school we had a fund drive for the Holy Cross Missions, and one of the prizes was the opportunity to go to one of our classmates house, his family had a color TV (very early 60's). The show we watched was Sing Along with Mitch.
And when I was travelling with my parents to New York, we stopped at a motel in Petersburg, VA (The Roses of Picardy Motel), and they had a single color TV in the common room, which the guests were able to watch. It was The Price Is Right, that's the one I remembered seeing. This was in 1958. They had the color turned up so it was quite garish. I loved it!
