Basically, you can obtain four globes of each colour. Three of the four you can use and one - you can not (in inventory screen try to put globe in QuickItem slot - there is one globe of each colour that you won't be able to put there).
So, you should place non-usable globes of each colour in the pillar of the same colour (red globe in the red pillar, f.e.).
Of course, you can place there usable globes too, but why waste them if there are not usable available - it is better to save usable ones for yourself.
In any case when you fill every pillar with a globe the puzzle is solved.
Hope this helps

P.S. No sequence, place globes in the pillars in any order - this doesn't matter. Each pillar must contain globe of the same color - that is all.
