For filtered question lists, if seems that new questions have background colour applied until I have actually seen them in the list. On successive viewing, it is no longer present.

However for Arduino lists of all questions, I can find no rhyme or reason to the use of such. When there is background colour, I can see the question in the list or even open it, but there is no change following this. What am I missing here? Surely it is intended to impart some piece of information. I had read many FAQs and questions, but can find no reference to such behaviour.

    Favourite/ignored tags are the only thing that alter the background in question lists AFAIK... do you have any favourite/ignored tags?

I now see that this is the result of having favourite tags.
