Although the black bar always appears in any description of colour bars, I'm sure that I've seen broadcast colour bars which end with the blue bar or just a small part of the black bar.
In this particular non-broadcast case, it would be easier to dived the line by 8, giving seven 8µS bars. The blanking period, though, is 12µS which would account for the first bar, blue in this case, being ~4µS narrower that the others. However, that doesn't explain what that clutter is to the right of the 'white' bar so, perhaps, I'm wrong ...
