A reasonable question. The definitions for those groupings are not really quantified, and so interpretations and results will vary.
But I have traveled extensively for work, family, and recreation. Among the states in green on my map, I have made multiple prolonged visits to all of them, with cumulative totals numbering in weeks (or even months) across the various trips. Also, I have indeed lived in several of those green states. Thus, although the categories are defined somewhat vaguely by that mapping site, I would say that my green-state results fit the criterion of states you've spent a great deal of time in on multiple visits
More difficult was my decision for a large state like California, in which I have made multiple explorations of the northern portion - but not the southern. I almost left that one as blue. On the other hand, I've seen a greater proportion of Delaware, but I've only made a few trips - amounting to less than a few weeks.
Alaska, Maine, and New Jersey are the only US states that I have not visited at all, and I'd like to explore each of them eventually. Of course, I should spend additional time in Atlantic Coast Conference territory, as well as the Pacific Northwest and the Great Plains. Like you said, there is much to see.
