The Closed Captioning System for the Deaf - which became known as "608" - was always capable of displaying captions in color.* However, this faculty was largely underutilized, due to a variety of historical / technical reasons.**
* Indeed, the first test broadcasts from 1979 included color.
** This is due to the design of the original 1980 "decoder," which only 'worked well' for color when installed inside an NTSC television. For the external adapters, grayscale instead of color was displayed. The only way to view color captions in color back in 1980/1981 was with a TeleCaption TV - and there was only one model ever made.
