How should I position the levers?

Hint 1 of 9:

The answer to your question is here in the room.

Hint 2 of 9:

It's somewhat coded, but if you pay attention, you should be able to find it.

Hint 3 of 9:

Notice that the levers correspond to five colors: green, red, blue, yellow,
and cyan.

Hint 4 of 9:

So look for a pattern in the room with these colors, but no other colors.

Hint 5 of 9:

Actually, one of the five colors will be missing.

Hint 6 of 9:

Go to your right as you're facing the levers, and look at the color wheel
drawn on the pedestal.

Hint 7 of 9:

Both the colors of the wedges and the relative sizes are important.

Hint 8 of 9:

Green, red, blue, and yellow are all pictured here, but there's only half as
much red.
