**No, you can not use black, red, and/or green cards in a Genku commander deck.**

What matters for commander deck construction is color identity:

> 903.4. The Commander variant uses color identity to determine what cards can be in a deck with a certain commander. The color identity of a card is the color or colors of any mana symbols in that card’s mana cost or rules text, plus any colors defined by its characteristic-defining abilities (see rule 604.3) or color indicator (see rule 204).

Genku's color identity is white and blue. Color words don't count.
