Everybody's Talking or The Family Game might have indeed been it, but there was another ABC game called One in a Million that was in BW for its entire run. Whichever it was, it was certainly one of the ABC games because they were more cash-strapped than the other networks and had more BW shows in daytime in 1967 than the others. NBC kept airing Concentration in BW until early November of 1966 because of Norm's determination to keep the rebuses two-color, and it was after that show went to color that NBC was all-color except for the occasional movie, news special or unsold pilot. CBS daytime went full color in 1966 or 1967, and ABC's earliest color games were Treasure Isle, The Honeymoon Race (which came out of Supermarket Sweep) and newly-converted Dating and Newlywed Games.
