Pillar of the Paruns and Reflecting Pool

[LotusHead]

Reflecting Pool - Land

Oracle text: Tap: Add to your mana pool one mana of any type that a land you control could produce.

Pillar of the Paruns - Land

Oracle text: Tap: Add one mana of any color to your mana pool. Spend this mana only to play a multicolored spell. 

Can Reflecting Pool tap for 1 mana of any color with no drawback? or must it only be used on multicolored spells?
Thanks in advance!

I lean towards the no drawback, but I really have no idea.

It looks like you get one mana of any color with no drawback.  Sweet deal!

All the reflecting pool cares about is what colors the pillar can tap for.  Any special restrictions on what the pillar's mana can be used for are irrelevant.  So, with a pillar in play, your reflecting pool will tap for all 5 colors, yes
