As usual the Minister for Misinformation is a little confused.
Apollo 11, the first manned moon landing, used a BW slow scan video camera.
So there was no possiblity of seeing a broken colour image as there was no
colour video camera on the moon. Subsequent colour images are either stills
from the 70mm Hasselblads or 16mm movies from the Maurer DACs.
The first colour video camera flew to the moon on the Apollo 12 mission in
December 1969. It was Al Bean who accidently pointed it at the sun
rendering it gubbed. This was a double shame as full time regular colour TV
broadcasting commenced in the UK a few weeks before the Apollo 12 mission.
Sales of colour TVs were brisk with customers looking forward to seeing
coloured images from the moon. (Full time colour UHF TV started in November
1969 in the UK although part time transmissions had been occurring on just
the BBC2 UHF sevice since 1967.)
