Only in later years green ones appeared and yellow with black stripes.

It was probably an H grade rather than HB. Pencils in the US stores often come out smudgy to me ever since then...
Looking it up, apparently this has something to do with pencils being manufactured in early (1920s) USSR by an American entrepreneur:

Eventually the Soviet government bought the entire operation from him, and thenceforth it became this:

And they probably just continued to use yellow, because why not?
The standard pencil we had at school was just plain red with a straight cut top so you could see the graphite - I think a staedtler HB (bit like [1] but didn’t have the ‘minerva’ brand name on it). A lot of automatically marked tests needed 2B pencils to mark the answer sheet and we almost always used the red and black striped ones like your link.
