gradient editor randomize button working from a number of drop colors. Spread and sqeese option

I like  noise gradient option but  tweaking  HSB  range  for color selection is somehow tiresome.   Would be nice to just drop a few complimentary colors  there manually.   Maybe a special 3 point complimentary colors widget.

  Also I would like a kind of scale gradient option  when I could select a  part of a range  and  spread or squeeze it  around certain  chosen point .

That all would be super helpfull for colorizing initially b&w  design or photo.    AI is nice but it never does what you really want .
