how do you counter the "protection from black" ability in magic the gathering

[Seismic]

how do I counter the protection from black ability in mtg?

[DatAsh]

With cards that change colour words, like Glamerdye.

[Void Elemental]

Or those that remove abilities (ie. Humility, Humble, Sudden Spoiling, etc.).

[Arix]

Old Man Snitches!

[Teddy]

Old Man Snitches!

would that card work against progenitus?

[Arix]

No. Protection from everything is not the same as protection from black.

And aside from anything else, you can't target Progenitus with the ability. Because, you know, protection from everything.
