You are right, up until now there was no real support for custom
colors because the documentation of PlotKit in this area is lacking.
This is fixed with PlotKit-pmm.8.

You are now be able to do:
aChart layout  options colorSheme: PKPredefinedColorScheme light.

There is now also PKCustomColorScheme that allows you to specify
manually the colors  with Squeak Color instances. Color class >>
#wheel: is a good starting point.
