In the Oculi crafting menu there is a "Tip" button that shows some basic recipes:
According to the first recipe, any three Oculi of the same color and size can be crafted into an Oculi one size larger.
By the looks of the second crafting recipe, the two primary colored Oculi can be combined into a secondary colored Oculi of the same size.
What about the third recipe? Can any three different Oculi be combined together for a White oculi? Or do they have to be Red, Green and Blue or Magenta, Cyan and Yellow?
