It has always been my understanding that producer Derrick Sherwin discovered in 1969 that 'howl around', as a feedback effect, was something which only occured on the old 405-line b/w tv cameras, but did not occur with the newly introduced EMI 2001 625-line colour cameras. I can't say I've heard that given as a reason before, and I doubt that it's correct as the howlround effect can be achieved even with modern video cameras. Using colour in the picture certainly adds nothing to the effect though. It really requires a good, high contrast monochrome image to work well.

Here are some letters from some former BBC staffers that did the work. Taken from Prospero - the newspaper for BBC pensioners.
These might make some more interesting reading on this subject. The obituary for Norman Taylor (March 2011 issue) that the first letter refers to is included as a separate attachment.

When experimenting with a colour camorder most colour patterns evenutally turned to white so I guess colour wasn't so good with the effect. I will add a link to Youtube of some of my efforts.

Here's my efforts from a few years ago.

Maybe it was not because it was a colour camera, but that that particular model had features that did not suit the technique. Gain control and contrast or latency on one tube being greater than others (the colour comet tail seen on some shots at that time) for example.

This, it appears, is the reason why the howl-around sequence for the 1970 season's titles had to be recorded in black-and-white, since it was only possible to create the effect using the traditional b/w tv cameras, which were just then being taken out of service as BBC1 went over to colour, in November '69. Video feedback happens with any video camera pointed at its own monitor. Based on the Bernard Lodge interview on the Spearhead DVD, it sounds like it was more a question of the characteristics of the feedback, that the old cameras gave sharper, crisper images. My guess is that had to do with miniscule alignment and latency issues with the color pickup tubes which contributed to smearing and a less striking effect. From my own experiments, it was difficult to control how the color patterns manifested, whereas monochrome was much more predictable. This may have been an issue then as well.

"The new digital issue of the Radio Times, available iOS on Appleās Newsstand, celebrates the dawn of a new Doctor with exclusive additional Doctor Who content, including a digital reproduction of the Doctor Who 10th Anniversary Radio Times special. The 68 page supplement was first published in 1973" and it got me thinking about something - always a dangerous thing - 'cause it looks different to the 1973 edition that I have seen. This Radio Times Special of the 10th Anniversary was reprinted in 2003 and has different photographic content on pages 2 to 5. These are the images used in the recent digital version. What is interesting to me is the difference between the original 1973 and 2003 reprint. Please see the comparisons of pages 2 and 3 below, that show the screen captures of two different opening sequences. This new sequence began in Season 11 with The Time Warrior first broadcast in the UK on 15 December 1973. So, does the original 1973 edition use a prototype work-in-progress version for its photos? And then, when the 2003 reprint edition was revised, was it done to show the actual opening sequence? Sorry about the quality - not my scans, and I did not attempt any colour corrections.

Huh, those differences are interesting. It seems much slower-paced, so I wonder whether the "flying daggers" part was added later. Would be nice to ask Bernard Lodge about that.
