Seriously now and Deede, you can get a (Double) Rainbow with Plant and Gold because it satisfies the four elements rule. Plant contributes Plant (1), and Gold contributes Fire (2), Metal (3), and Treasure (4), resulting in four distinct elements in the breeding pool, which satisfies Rainbow's requirement.

Lily, you got a Rainbow from two Monolith 1s because the Monolith 1 dragon contributes Earth (1), Water (2), Plant (3), and Monolith (4). It contributes the Monolith element as well so that when you have two as a parent, any can be a result.
