Painter's Servant + Soul Spike

[Cavius The Great]

If I have a Painter's Servant in play naming "black", could I discard two land cards to pay the pitch cost for Soul Spike? To simplify things, are lands "colored cards" in addition to being lands with a Servant in play?

Yes.  You can also pitch artifacts.

[Anusien]

No, but you can remove two lands in your hand from the game to play Soul Spike.

Painter's Servant |Artifact Creature -- Scarecrow| 1/3. As Painter's Servant comes into play, choose a color. / All cards that aren't in play, spells, and permanents are the chosen color in addition to their other colors. SHM-R

Thanx for the feedback guys. I assumed it worked that way but just wanted to make sure.
