I was actually partial to this view, myself. Purples seems more like a hybrid, and plant is also a hybrid of the resources that are water and sun.The riddle says "" (red) "" (as in red's) "" (purple) "" (pink, which is just some other colour). However, pink could also be seen as a hybrid of red and white, though I would see that as more of a variation. This takes it to mean that "" is a separate item, not a descriptor of the hybrid.The riddle says "" (sun, think of the Allegory of the Cavern) "" (as in the sun's) "" (plant) "" (water, because sun+water makes plant). Also, as Alpha mentioned, water is clear, but I'm not so sure that is part of the riddle itself. This takes it to mean that "" is a descriptor of the hybrid.

As Jorick mentioned, Pink is a hybrid of Red and Purple. Also, the core of the riddle [i]is[/i] the beginning, middle, and end part.
