Any colorless mana that's produced isn't affected.

Wotc — August 23, 2016

This has the supertype world. When a world permanent enters, any world permanents that were already on the battlefield are put into their owners' graveyards. This is a state-based action called the "world rule." The new world permanent stays on the battlefield. If two world permanents enter at the same time, they're both put into their owners' graveyards.

Wotc — October 01, 2008

Although the color may be altered, any restrictions on the use of the mana are not removed.
