The transition from yellow to red should show some orange, but it seems to show red OR yellow instead.

It looks really awesome, but the color mixing isn't working very well. Somehow unpredictable...

Is the color the same inside and outside of the part? Or is it red inside and yellow outside and vice versa?
Is it the original diamond hotend?

I wonder if that's due to the colours being mixed? I don't know what the OP is using, but maybe they're Red, Green, Blue where Cyan, Yellow, Magenta would be better? Or maybe one of the colours isn't the exact right hue?

Would a longer melt zone allow the colors to mix better? I would think it would since the filament would be spending more time in the heating area of the nozzle.

I wonder about threading the inside of the nozzle, so that the molten filament swirls as it comes out?

The size of a chamber is only relevant because the slicers are not up to the multicolor task yet. Only the outer perimeters have to have a defined color while the rest( like infill and support ) could act as color change area too. The slicer would need to know how much filament has to be extruded before the "new" color is mixed.
With a bigger chamber I would ignore the higher filament cost if I get a sharp and true color change as benefit.

That works for some models, but assumes that colour changes only happen in Z. For colour changes in the XY plane things get a bit more difficult, although... I guess I'm making assumptions tooMaybe it would be possible to print a segment of 1 colour, move away to print some non-visible area or into a purge area and then return to continue the perimeter in the new colour. Man, there sure is a world of possibilities to explore here!

While that's certainly true in general, it doesn't matter too much when printing cylinder-esque objects like the example shown. If all the colour changes happen at the nozzle exactly 10mm (say) after the change is made, and all printing is done in a(say) a clockwise direction, then all that happens is that the colour change is rotated by 10mm around the perimeter of the object.
