Rainbow Art/Rulings


 * While you can return colorless cards to your hand with this ARTS, because colorless is not a color, you may not select colorless as a color for Rainbow Art's secondary effect.
 * Regardless if the card has Multi Ener because Multi Ener only pertains to payment of cost.


 * You cannot select the same color twice, and therefore cannot activate the color's effect twice.


 * You can still activate this ARTS's secondary effect if you are unable to return either a spell or SIGNI. In this case, you can only select 1 color.
 * If either there is no spell in your trash or no SIGNI in your trash, you still can only return 1 of each to your hand.


 * You may select the cards paid from the Ener Zone to the trash for this ARTS's cost and return them to your hand.


 * You must resolve the effects of this ARTS in the exact order they are listed.
 * Therefore, you must first check the red color effect, then green, then blue. You cannot change the order, such as green's effect then red's effect.
