Protection and color choices

[Destore117]

Say I'm facing an artifact deck (or using one)
Can I say colorless as a color to get protection with a card like {Brave the Elements} or add mana with a card like  {Caged Sun}  {Coldsteel Heart}

No colorless is not a color, when it says color it wants one of the five colored mana
