Not really. Most traditional photographers either tried or went color in the '60s. Some traditionalists insisted that real, serious photography was only done in B&W. This sentiment carries on to this day with film photogs. Some continue to think B&W is serious and color is for pop/sugary stuff/commercial.
Color was a bit more expensive but I don't think that was the main driver. On the other hand, if the photo was for mass circulation/publishing, printing in color was more expensive --but the photography itself not so much.
