color schemes we need to copy out hash tables, what is way much easier with the COW concept of the Qt containers. Also: according to https://tessil.github.io/2016/08/29/benchmark-hopscotch-map.html QHash seems to be faster in the most relevant category "Random full reads: execution time (integers)"
