I am aware of solarized, I do use it for terminal; however I don't think
that is a good solution here.
I wanted a general solution that would work irrespective of the used colors
- so it would for my custom visualizations, as well as roassal examples.
I don't think that this is possible to achieve via interaction, because
that would mean overriding every single shape.
So maybe subclassing TRMorph and having TRDarkMorph with overriden drawOn:
method? That way the original TRMorph would remain intact and this new dark
behavior would be supported.

Hi Peter!
What your propose make sense and deserve to be carefully considered.
Instead of modifying TRMorph, maybe we can have an interaction for this?
I am not so keen to modify TRMorph.
Also, there exist some color palette that produce good results when use
with a white or black background:
